I bought my ps3 about 3 weeks ago (40g), I now own 5 games : Warhawk, Virtua Fighter 5, Virtua Tennis, Assassin's creed and Uncharted. Well I just ended Uncharted and assassin's creed and I'm thinking of buying new games...

Anyway I love RPG's and the only RPG out there for ps3 and that I truly like is Oblivion, the only problem is that I already played about 100+hours on the original pc version (without the expansion) and never actually ended the game. So here is my Dilemma should I get Oblivion's GOTY edition for ps3 (is the expansion worth it to play all over again?) or should I wait for other games that are about to be released such as Turok or DMC4???

PS: Please keep in mind that I'm looking for a game with content and some gaming hours, not something that keeps me occupied for only a few hours...

Actually those are not bugs (I think), they are called in-game minigames that can be triggered with a combination of certain actions, like killing a certain type of monsters or even obtaining x items...

About the invulnerabilty, i can't say for sure if it's one effect of these minigames or if it's a gear effect.
