None whatsoever. I'm weak. Fragile. I cave under pressure. My name is Brian, and I have a problem. I was lured by the evil temptress that is the 360.
I finally bought the system yesterday after playing OutRun2 on the original Xbox and craving some Ridge Racer action. Plus, I really wanted to see what all the fuss over Geometry Wars was about. So I bought the system, Ridge Racer, Burnout Revenge, and a couple of Xbox Live Arcade games (Marble Blast Ultra and Geometry Wars). I also had to throw away $100 on the wireless adapter because I don't have an ethernet port in the room that I play in. I mistakenly thought the 360 was wireless out of the box.
Overall, I'm pretty impressed with the system. Aside from the extremely loud hum when running games and the huge-normous power supply, it fits nicely next to my other consoles. I don't have an HD television yet (and won't for some time), which makes me a bit disappointed because I've seen what the system can really do if given the opportunity. I'm also glad that there aren't really any titles coming out soon that I'm dying to get, because I've pretty much exhausted my cash supply until the Revolution launches (which will, again, exhaust my cash supply).
I'm just getting the hang of the whole Xbox Live thing, so if anyone over here on GameSpot wants to meet up over there, my GamerTag is (not so surprisingly) DrFish62. The only thing I ask is that you include your GameSpot username in the friend request so that I know who you are. I chose the Atari symbol as my avatar because I wasn't given many great options to choose from, and I thought it was ubiquitous enough so as not to attach me to one game.
I think Ridge Racer and Burnout will keep me busy for a while. I'd like to get PGR3 at some point, and then possibly Kameo, Oblivion, and Tomb Raider when they all drop (significantly) in price. I'm just not willing to pay $60 for most of these games yet.
