I figure I would update this thread a bit since I had a chance to play a few more games and put in a bunch of more hours on my brother's PS3 before leaving.
My brother maxed out his Visa paying his tuition (I think, he's a big of a degenerate so he could have spent it on booze) so I did not get a chance to check out any PSN games. That game with the animals running around a post apocalyptic Tokyo seemed very intriguing to me. Actually, Japanese games in general are very intriguing to me since it's another culture's take on gaming - believe it or not, it's been 14 years since I played a Japanese game that wasn't a fighting game. That game? Chrono Trigger.
I checked out Metal Gear Solid 4 - too many movies, turned it off quick. I also feel like I would need to play the previous MGS's to follow the story so much of the allure of this series is lost on me.
Uncharted: Drakes Fortune - Very cool game. Borrowed it from my brother's friend. Did not finish it but it makes me feel like Indiana Jones. It seems like a very linear experience that I wouldn't be able to play more than once though - I tend not play games twice if the story outcomes are the same everytime.
Beatles Rock Band - Alright, this was by far the most fun thing I tried and I don't even like karaoke (I was on the mic). Even my mom liked this and she's a 60. I understand that music games are on hiatus due to Activision running the genre into the ground but I think the genre could probably survive being platform independent.
There were a couple of PS2 games I wanted to try - namely Shadows of the Colossus since people hold that in reverence as much as PC gamers hold Planescape Torment in reverence but I did not have the time and had to go home. Plus, my brother has one of the newer PS3's that don't support backwards comparability (this by the way, makes no sense to me, why remove features as you update your console?).
So ends my PS3 experience. Very happy I finally got to try out a console after all these years. As for buying a PS4 or Xbox 720, I'll probably skip out on the next console generation as well since it would require me to buy a television. I'm content just watching from the sidelines as a curious observer.
