ME2 - mineral mining suckage
Daikatana - the stupid ai partners kept doing stupid stuff(getting stuck, not reacting to enemies)
Mask of the Betrayer- the soul eating mechanic feels forced for story purposes
QTEs in any or most games
AssCreed 1 - you cant swim!
Asscreed 4:
1)boarding action crew counter:the number of the enemy crew is meaningless because they spawn endlessly depending on who you have to kill or what you have to destroy(barrels) or get(flag)
2)tailing -the fact that enemies have eyes behind their head or can spot you form really weird angles inspite of you being in cover/line of sight is broken, the games not following its own rules
3)weather - its seems to change at the drop of a hat to make attacking certain fotresses harder
Farcry 2 - mallaria, vehicle overheat, notoriety:at some point it seems everybody in the whole area just shows up out of nowhere to try and kill you
FallOut 3 -VATS, game doesnt have true ironsights
Any game:Forced stealth sections where you are buck naked
Diablo2 - corpse retrieval becomes a hassle at higher difficulties with high enemy mob density
Elder Scrolls:
1)the skill leveling system -grinding is unimaginative
2)super guards - they show up even underwater, hive mind makes them aware of your crimes regardless where crime/s were performed(skyrim tries to fix this though)
Ultima
agan - jumping
GTA/Driver - scripted chase sequence, you cant block the other guy's car by parking in front of the getaway vehicle, the game moves your car elsewhere
