Nah, actually I don't remember a single game where I considered it as big an annoyance as most others here seem to. It's hard to find a game where this feature is more than an annoyance though, where it actually contributes to the gameplay. I think Bet on Soldier did a great job of implementing armor repairs into FPS gameplay but well, it's an FPS, additionally its "you have to pay for everything" philosophy seems to have pissed off everyone except me. :P
