Just a place to catalog all the man-hours lost to bugged save systems, glitches that strand you unable to complete the game, or games that just didn't play nice with your memory card.
My earliest experience with this particular circle of hell was in Wasteland. Fishing around in the sewers earned me the wrong part, so I couldn't repair my robot or go take out the military base. Game over, fuck you for playing. Of course, we're talking about Wasteland. I started over, level-grinding a new bunch of losers into elite commandos who can eat Terminators and shit the little robots from Batteries Not Included. And finally beat the game. But I'm still bitter about it.
More recently, I've lost hours of progress in Gun for the PS2 because I saved in a section where, if you manage to get killed, the game leaves you with no way to retrieve your weapons and continue. You have to kill a specific enemy to get them back, and when you reload or retry, the guy is already dead and his body removed. Yet another reason to despise any design team that uses the tired old "captured and disarmed" level in a shooter to force the player into using otherwise boring and lame weapons.
Sure, I could've avoided some of these problems by duplicating my saves constantly to another memory card. Unfortunately, this is a fair amount of trouble in many games, and most do not have such glaring quality-control issues. So I get complacent, and occasionally suffer for it.
What are some games that have burned you?
