Hold on let me check my games collection...
Yeah Far Cry 2, i tried to like it again this year but all the small bad design choices just came together into one big "fuck this i'm out"
You can't stealth anywhere, machete kills alerts people to your presence (rather than say being silent as you'd expect,) They like to throw enemy jeeps at you far to often, the driving is shit (since you'll be staring at a map 80% of the time) and is friendly AI really that hard Ubisoft?!
Oh and if all the cars get blown up during your attack of a random fortress/farm/airfield/what have you, enjoy your 40 minute hike back to the nearest car...
On the bright side actually attacking a fortress is quite fun! So that's 10 minutes of fun followed by around an hour of the shit described above before the next 10 minutes of fun
Also LA Noire, specifically the ending. See this is why a team of writers is infinately better than just one guy (correct me if i'm wrong but i'm sure LA:N was written by one guy)
