Yeah I was initially extremely mad with RAGE on PC. All kinds of issues, I ended up getting frustrated on that first day and just not playing it after the umpteenth crash. However, I've been keeping abreast with the custom config files and all the other little fixes, and combined with the latest patch, the game is actually running more or less flawlessly for me now and the only thing that still bothers me is the poor texture quality up close - but I just try not to look very hard and then it's all good.
I'm actually really enjoying RAGE. Just did the Dead City and many fun side quests like taking out the shrouded bunker. I'd actually have to say, overlooking the terrible technical issues at launch, this game is probably a good 7.5 or 8 to me. Any game that I look forward to playing more deserves at least that in my opinion.
