Similar games to no-life before The Witcher 3 comes out..

Play Witcher 1 and 2 then export save to 3 (if it will be possible) ;)

That would be awesome! Might try that out indeed!

Play Dark Souls :P It's filled with content (and death)

similar as in... open world? or deep rpg? or wut? I mean... gta V is the most living open world to date with plenty to do.

I'd suggest witcher 1 and 2 definitely.

You may also take a look at Mount & Blade (Warband), but it's RPG mixed with strategy.

gothic I and II (the 3 is not a great sequel ) as suggested above and if want to play also old games I suggest Sacred

Thank you for the suggestions everyone! I'm gonna look trough them all and find what's best to no-life and kill time..

Have you heard of a game called Skyrim?

There are some great mods for it you could try. Only 5.99$ for most of them, which is pretty cheap.

You should download Shenmue and play it on an emulator if you haven't yet.
