The most recent game to piss me off was last night actually.
I'm playing Ratchet and Clank Future: Tools of Destruction and I've gotten to the final boss battle. Damn thing's hard to do when you're high off of blood loss (donation, not wound) and it's 2 in the morning.
Reason I haven't beaten it and bought Crack in Time yet: I didn't have a PS3 when it came out, and then Crack in Time was 60 bucks and I had only just gotten Tools of Destruction. I mean, I am a die hard Ratchet and Clank fan, but 60 dollars is just a bit too much right now. I think it's gone down though, so now I've about beaten this game I'll get the other.
