Good Open World/RPG/Replay-Value Games?

A personal recommendation i can make is Middle-earth: Shadow of Mordor Game of the Year Edition . Its has a very good sale price too :D

Witcher 3 and Skyrim are your biggies in this category. Other cool titles to check out: Just Cause 3, Mad Max, Far Cry Blood Dragon, any Far Cry actually, Gothic games, Vampire The Masquerade Bloodlines (get the community patch), Sid Meier's Pirates!, Sleeping Dogs, Mount & Blade, Deus Ex, and that's all I can think of off the top of my head.

I'll recommend Dragons Dogma. While not as open world as you may like it, and with a certain sense of linearity, you can do plenty of roaming without the games express say-so. Fond memories of disregarding early main mission objectives to go help villagers, or just go explore some little area that turns out to lead to an entirely new zone. Can be deceptively hard at times, but I had a blast. Sort of like an easier-access Dark Souls with more arcadeish combat that requires less intense timing, but still feels dramatic and awesome.

I never actually even got that far due to backing up the save folder and switching it out so I could run several different characters at the same time. I still haven't decided which I like best, as they're all pretty awesome. Hnng.

Give it enough chance for you to get through the tutorial, which has you playing a generic knight type and shoves you blindly through a bunch of stuff it doesn't explain very well. Once you're a scrappy little villager then that's where the game actually begins.

Different levels of RPG elements, replay-value, and open-world qualities, but some essentials that haven't been mentioned yet:

• Fallout: New Vegas GOTY
• Any Borderlands game
• Fallout 3 GOTY
• Dishonored
• Batman: Arkham City or Batman: Arkham Asulym
• In terms of classics, the Stalker series (good bundle) and, thematically connected, the Metro series (also has a bundle I think)

From what's already been proposed I would give my two cents to Vampire: The Masquerade - Bloodlines (with the fan patch for sure), Sleeping Dogs Definitive Edition, Shadow of Mordor GOTY, some of the more recent Deus Ex or Far Cry games as well.

Looking at the prices, Shadow of Mordor GOTY / Dishonored / Arkham City / Borderlands GOTY are probably the best options IMO, in that order. New Vegas is a steal at 2.49€, but the GOTY edition is 9.99€.

Side-note: Shadow of Mordor GOTY + Arkham City or Asulym = 8,98€, crazy price for the amount of hours you can spend with these two games.

Kingdoms of Amalur: Reckoning because it simply isn't mentioned enough.
You can get the full game + all DLC (no further DLC will ever be released) for a mere $9.99 USD.

New vegas, Skyrim. If you get those games, try to get the complete editions (with all DLCs) mostly because mods. You'll need to mod both of those games for the best experience. I personally prefer New Vegas.

You want the three of those categories in one game or a game per category?

Darksiders II

If you don't mind difficult games, Dwarf Fortress is open world game with tons of replay value :D

And its free.

Deus Ex 1 > Deus Ex HR (cant say anything about MD, but IW is pretty bad)
Borderlands 2 is a lot of fun, but you might want to play it with friends
Dark Souls 1/3/2 (in order), but you might find it it hand/challenging

Since no one said The Witcher 3 I'll say The Witcher 3. It's massive, gorgeous, full of great characters and tough decisions and can still surprise you even on the 3rd playthrough. Also, you need a minimum of 4 playthroughs to see all endings, as there is no final choice you can save before and just reload - the ending is determined by the choices you make throughout the game. It's really what every choice-and-consequence game should aspire to be.

As for price, it's only 40% off right now which still leaves it at $24. Not the cheapest game you can get, but it's completely worth every penny

Gothic 1, Gothic 2 with expansion (prolly best of the 3 games), Gothic 3 with community patch to fix the buggs. (also has one of the best soundtracks ever)

I see you played Path of Exile for less than one hour, don't know if you play it on the stand-alone client.
It's not open world, but it's very replayable. In a month or so there will be a great expansion which will add six new acts and remove the normal-cruel-merciless difficulties thing, you will have a single playthrough before getting to the endgame maps. There are tons of different maps with different areas and bosses, you can apply the modifiers you want to get more challenge (and rewards).
Don't really know if it's your cup of tea, but I can assure you the game really starts once you get to the endgame maps. As you know, the game is free, so trying doesn't cost anything.

Edit: forgot to say that areas are randomly generated, so every time you open an area, it will be different.

shadowrun series has also replayability (Probably not boston and less of all returns).

Dragonfall and Hong Kong are great RPG (turn based combat)

Replayability on a open world game? Uff... If I play a game 100+ hours I would definitely not reset my progress and start from the beginning.

+1 for every borderlands game. Also definitely Dying Light...if, like most people, you like killing zombies.

Bought Miscreated, mainly because my friends play it at the moment. Hopefully the devs keep the updates coming.

fallout 4
dishonored 2

I'd say Monster Hunter World is the best of 2018. It's also the only one to show up when I do this.
