Haven't had any problems with my 360 getting too hot, and I've played for many, many hours straight, with no issues--and Oblivion is very addictive
.
I use mine for DVD's, games, streaming movies from Media Center, and everything else I can think of. I think it is great.
And may I recommend Kameo, wow, it is kinda lame--"The Watnot book"--but it is a pretty good game, not to mention it is cheap, got mine for $27 at EB Games, yes it was used, but hey the used Oblivion was $54 when the new one was $59.
I too rented Oblivion, $5.99 for 7 days at Hastings, and if you look at my gamerscore, I only got 120 Gamerscore from those 7 days--I didn't get very far into the game. I am going to wait until I can afford and/or the price comes down to buy it so I can have it.
But yeah I agree, I usually rent first so I can be sure that I'll like it, but this game needs more time than what you can get from renting it. Got to warn you though, Oblivion doesn't catch you right away, you have to play for a while for it to fully suck you into it, lol. At first I didn't think it was that great of a game, but after a little bit of playing it, I found myself enjoying it more and more.
