Recomend please some games.

Ghost 1.0 is a pretty neat metroidvania.
Cave's catalog is on sale, so if you like shmups, you can't go wrong with Mushihimesama.

RPG

If you are okay with jRPG, then Trails in the Sky is a must have.

Platformers like Megaman.

There's Rosenkreuzstilette if 40% is enough of a cut for you.

added for talking

Wuppo.
Valdis Story: Abyssal City.

Azure Strike Gunvolt.
A.R.E.S - Extinction Agenda.
Shovel Knight.

The "Momodora" series. The first 3 games are free, I think there are two or three newer ones available on Steam.
Bloodstained (Both of them, though I think one is yet to be released and I'm not sure if it is yet available on Steam).
Dead Cells.

City Building:
Cities Skylines
Block'hood

Tower Defense:
honestly any of the Kingdom Rush are good
Dungeon Warfare
Creeper World 3
Defense Clicker
Defenders Quest Valley of the Forgotten

Chrono Trigger-like:
Forever Home actually really really well done. No BS fetch quests or grinding, very likeable characters and story. I actually won here, and am still making my way through

RPG:
Elex

RTS - just a couple of the newer titles released:
They are Billions
Ancestors Legacy
Microsoft RTS Bundle
Rusted Warfare

edit: added some platformers below

Platformers:
Rabi-Ribi

Valdis Story

So he got suspended for "begging" , hope this is not abuse of new power...

Why did he get suspended? He was just asking for recommendations not for giveaways?

I'm going to answer the question anyway in case you still want to know when you get back. If you did get suspended for begging, I really didn't get that impression by your post.

Anyway, from your wishlist I suggest:

Witcher 3: It's a must play if you love RPGs. You have to get the game of the year edition though because I actually loved the two DLCs more then the main game itself.

Bastion: Good narration and combat. Nice story. Overall solid game.

Steamworld Heist: If you like turn based strategy then this one is great. Also has manual shooting to practice some fun trickshots. I love the art, the characters, the hats. It's just fun.

Knights of Pen and Paper: This one is very grindy but overall fun. It doesn't have much story but it does make you feel like your playing a tabletop game.

Pharaoh Rebirth+ is a pretty cool metroidvania-style platformer.

Gunvolt is good Megaman-style gameplay

And Crimzon Clover is a good starting point if you ever feel like trying some proper bullet hell. As in the sub-genre of shmups, not stuff that shows up if you browse for the "bullet hell" tag on the Steam Store.

"RPG alike Gothic, Skyrim"
mate u should try ELEX and Kingdom come deliverance

Thanks all for responses, and yep. I was not asking for gifts because i will buy myself.

If you liked Skyrim, you gotta play Witcher 3..

i can recommend final fantasy XIII and XIII-2 (the third isn't very great in any aspect) however this trilogy it's more focused on history than gameplay, that said, if you just want a good history and don't care about gameplay buy FF13 FF13-2 it's a bit better in gameplay but overrall this trilogy isn't the best of the series. but for the price listed of the three games you will have around 120-150 hours of gameplay.
i will recommend you buy the final fantasy X plus X-2 before the final fantasy XII trilogy, even final fantasy VIII have better history i can recommend this game too.

Don't buy never any call of duty game, they are always full of cheater and his policy of 50% discount it's the worst moneygrab in the market, games so expensive even 10 years old, PLUS the seasson pass with 4 multiplayer maps at same price than full game, if you want the full game you will need to pay 110$ in total.

Divinity original:sin for that price it's very great if you like to read a lot. you can play this game 30-50 hours easy, also have co-op so you can play with friends the same game, plus strategy game, i don't finished this game but i don't get bored playing it.

from your wishlist can't recommend anymore.

TOWER DEFENSE GAMES:

i like a bit this type of game too but never enough to finish the game however there's one game that was great and it's Prime World Defenders, you can even get in the trade forum of steamtrades.com was a bundle game time ago, maybe someone still have one copy for sell.

PLATAFORMERS GAMES:

-Dust an elysian tail
-Shantae games (the first two was bundle games too, maybe in steamtrades.com you can find them cheaper than steam store)
-metal slug games (a clasic games for a casual game)
-Tomb Raider games (the first 4 the old games are pure plataform with puzzles and some combat (gun kills, don't expect the best combat they are old), there's some mods made from some users that make controller playable etc.... check them, they all was bundle too , you can get from steamtrades.com probably for a few cards each)
-Trine 1 and 2 both beautifull games, great soundtrack too and the combat it's perfect too, mechanics etc....
-Strider not a bad game
-Giana sister both games plataformers and dificult.
-Aaru's awakening the hardest game ever, frustrating sometimes,short, i beat it in 2 hours (i will never play again, but well it's good for a simple session of game)

CITY BUILDERS:
-Anno 1404 + expansion, mostly single player but it's a great game, have a campaing and some maps that ask you do things, you can even make your onw randoms maps choicing over a lot of options (from more easy to more hard situations etc.....), great soundtrack too isn't the first time i just sit on main screen to hear the soundtrack.
The IA isn't the best in this game even the hardest specially on combat (when they travel in ships to your territory, but you can always let them sit in your territory and don't destroy the ships for make it more dificult), this game it's let's focused on combat and more on city build.

RTS GAMES:
-Age of empires 3 it's good for a gast games compared with the rest of age of empires games, it's diferent and the same at same time, anyway good game with lost of expansions for single player play if you want do campaing.
-Company of heroes 2 i don't played a lot but it's a very good game and cheap in sales the full version with all DLC.

OTHER MARAVELLOUS GAMES

-Ryse son of rome: this game it's fucking magnific however you need a good PC for play it well, this game it's fucking awesome you really should buy it without think, just buy it.

-YS origins i don't know if clasificate this as a hack and slash or plataformer, just a good game too

-Lara croft and the temple of osiris and Lara croft and the guardian of the light we can classificate this as arpg plus plataformers both ultra good games and cheap in sales (buy all DLC too that add maps, no need to buy the cosmetics DLC if you don't want etc....)

-Remember me this games was a surprise because people talk bad about it but it's a hidden jewel it's a very good game too.

-Frozen synapse for single player purposes only as a strategy game, dificult to learn but can be very funny once you learned the basic, (the game have a lot of tutorials and you will need to do them before play) best soundtrack ever, the multiplayer you can play simultaneos games at same time, and every time the opponent make the moves you get a notification for continue that game, so you can play 15165165 games at same time.

-Skulls of the shogun funny dialogs and it's an strategy game

this are my recommendations that come to my mind at this moment, please let me know if you buyed any of this games, took me a lot of time to make this post and i just want to know if you like any of this games.

Tower defence: get Gemcraft and Kingdom Rush

Definitely get Defender's Quest.
https://store.steampowered.com/app/218410/Defenders_Quest_Valley_of_the_Forgotten_DX_edition/

It checks the Tower Defense and RPG boxes in the very best way.

From your wishlist and my Recommendations:
The Witcher® 3 Game of the Year - Worth every penny if you are into RPG. Its around 20-25 for GOTY.
Divinity: Original Sin 2 - Great RPG
Bastion - Heard great things, I bought it, yet to play it. I got the soundtrack version.
Pillars of Eternity / Baldur's Gate - Great RPGs
Balrum - Interesting RPG that you can craft

Northgard - If you want a current RTS, Northgard is fun.
Age of Mythology: Extended Edition - This is fun and there is a recent expansion but I recommend Rise of Nations: Extended Edition more also by Microsoft.
Warlords Battlecry III - Fun old-school RTS
Dawn of Discovery™/ Anno 1404 - Is a fun renaissance City/RTS builder
Darkest Dungeon® - Try if you enjoy vomiting, cursing and swearing the RNG infront of your PC
Dominions 4/5 - Is actually an extensive strategy game though pixelated. It is deep and lots replayabilty. Its too hard for me to get into though.
Warbanners - Interesting looking strategy, I recommended to another person today.
Slay the Spire - Overwhelming Positive Card Strategy game, high replayability.

Cheers, Have fun~

Thanks guys for your recomendations, i actually get Witcher 3 from your recomendations, and fair price on summer sale with expansions. Also get Vanquish.
