Well those arent 'unwinnable' just really fucking annoying and time consuming. although those are usally te best storys, in fact one time i was playing eldar against space marines and i was getting hit horribly, i was losing badly and i thought i wass going to lose. But as a last ditch effort i teleported a banshee squad away to the other end of the cliff and sent them to kill the AIs base, and i WON! battle was epic too once they got past my mine field.Mr Thin said:Yes, but it was more due to a lack of skill on my part than any broken game feature.
I was playing Dawn of War, an RTS if you don't know, and it was a 1v1 bot match, me as Space Marines, the bots as Chaos. We'd been playing for a while, and had gotten to the point where we were producing resources faster than we could spend it.
It basically got to the point where we both spammed units from multiple unit production facilities, and smashed them together in the middle of the map, in a constant, unending melee (that also included rockets and plasma).
This battle went on for over an hour, non-stop, neither of us gaining any ground, before I finally called it quits and exited the game. It simply would not end.
Oh right OT: I think Fallout new vegas once and any time i have to go back on a save losing a significant amount of progress.
