What is....?

Get Bastion, it's a really good game, and its story is awesome. Plus, it's cheap!

Mass Effect series, there's a good 250-300 hours in the trilogy.

Go play Stalker and download cool mod. For example: Lost Alpha, Misery, Arsenal Overhaul.

Dark Souls , have it on PS3 and going to get it this summer on PC .

Fallout New Vegas, Beyond Good and Evil, Rage, Just Cause 2, Mercenaries 2. Those are pretty cool open-world games =)

Favourite game? Monster Rancher Card Battle Episode II for the PS.
Favourite game that also happens to be good? The Typing of the Dead: Overkill
Favourite game that is also on sale (currently): DMC: Devil May Cry
Favourite game on a budget: One Finger Death Punch: 12 hours clicking 2 buttons ... No Ragrets ;P

Project Zomboid is a very realistic Zombie Apocalypse scenario game.

This War of Mine (but it's more an experience then a game)

Dark Souls

Mount and Blade Either original, Fire and Sword, or my personal favorite Warband.

Chroma Squad

Catacomb Kids

Castle Crashers and Battleblock Theater.

Speedrunners

Lethal League

Bleed

Dungeon of the Endless

Nuclear Throne

Hotline Miami

Binding of Isaac (Regular or Rebirth your choice)

Rogue Legacy

Gunpoint

and if you liked the aspects of looting there is

Torchlight (I and 2)

UnEpic

The FATE series

If you like the fallout games (the last 2) Then get the

S.T.A.L.K.E.R. Series

and if you liked the first 2 then get

Underail

The Eschalon Book Series (It's more medieval then futuristic)

Shadowrun (I would suggest Returns and Dragonfall. There is Lockdown, but you need to be online to even play it despite not really having mmo features. Think Diablo 3.)

Bastion and Transistor are highly related

Don't Starve is fun and has a great art style

I could go on, but I think I've taken up enough room and haven't mentioned a few games not mentioned by others.

Some of my favorite games:
-Psychonauts (pc)
-Dishonored (pc)
-Hyperdimension Neptunia Re;Birth1 (psvita)
-Akiba's Trip (psvita)
Currently playing or playing, and i'm enjoying so far:
-Star Wars Knights of the old republic 1, Battlefront 2 and Republic Commando (pc)
-Marvel Heroes if you like either Marvel or MMORPG's (pc)
-Nosgoth if you like Legacy of Kain or MMOFPS (pc)

Crash Bandicoot: Crash Team Racing

so much fun playing this game, so many pleasant hours. If my PS and PS2 hadn't broken down, i would still be playing it

Payday 2 - tons of heists and levels

I'm currently addicted to CS:GO.

Magikarp is the new potato.

don't blame me for my heresy

how about Tron 2.0. great fps with rpg elements highly underrated. and even better with the Killer App Mod.
of course the style of the game is a matter of taste

I can't recommend Dark Souls and Bloodborne enough.

Too hard?

Wot r u m8, casul?

Love, Baby, don't hurt me, Don't hurt me no more.
sorry i had to, no one else took that perfect setup.
game wise is hard though, people have already listed so much idk if i really have anything to add. i'll just leave now :-P

Insurgency.

Tomb Raider!

Since nobody else bothered to mention it. And Magicarp! ;)

...a man a miserable pile of secrets!
