Killing floor, if you are ready to spend 400 hours on this of course) Ok if for true is BEAT HAZARD. Just 20-30 hours of good game.

To The Moon, The Plan and Cs:go if ur good at shooting game's..

QuestRun

Sacred 2 :D do it, now!

Hero of the Kingdom. Casual, little clicky adventure game, story is quite good - but expect a lot of pixelhunting. You need to collect like everything from the map (mushrooms, fishes, barrels, crates, and so on) Also quite often bundled, you can get it cheap.

Brothers - A Tale of Two Sons, To the moon, Scribblenauts, All Lego games, Free 2 Play (Movie), Lucius, Blockland

Deus Ex: Human Revolution - Director's Cut.

Trust me. There's no chance of glitching any achievement like Foxies of the Hounds or Pacifist or Factory Zero and having to repeat the ENTIRE GAME to get them.

kinda braid is quite easy 100% achievement game ;3

The Walking Dead 1 and 2, you just need to finish it.
Among the sleep. Short game with just a few easy achievements
Secret Ponchos. 1 Achievement if you buy and play this during early access

So this stupid console trend is now comming to the PC too?
How many stupid PS3 and Xbox360 owners played a shitty Hannah Montana game just because it was easy to get all achivements...

If you want to impress your friends than do it with Achivements that are really hard to get. No one will praise you for getting all achivements in The Walking Dead.
And if you do it for your own satisfaction than try to get 100% in games you like and don't waste your time with games you don't like.
