"Please name 3 AAA titles released this year with obvious and none playable main game mechanic + that did not got fixed."

Nice statement, since the majority of games is mostly released at the end of year.

Not this year But:
Civ5: Savesystem for multiplayer is a huge fail. You can save to the steam cloud, but never load again. You can save a custom save during game by Ctrl+s(there is no menu button), but you cant load the save unless you copied it into the autosave folder and prefix the savename with autosave.

BadCompany2: Messed up engine. PatchbyPatch it changed completely: Working on Dualcore, not working on dualcore, working on dualcore....last patch long long time ago: NOT working (properly) on dualcore.

Knifing still not properly implemented. still possible to knife a camping sniper into the back multiple times without hitting hime o.O(though its less frequent)
