The Playstation 2 is a great system. But technically, it doesn't have the best graphics. Now, I am not biased towards any system, although I do like Sony brand the best, but doesn't mean I am biased. As we enter into the next era of consoles, a thing comes to mind though. I own a 30" LCD widescreen, and with that, alot of PS2 games have worse graphics than when on GC or Xbox. I was against the Xbox 360 at first, but with having a such great tv, I realized, what am I waisting my money for? I have one of the greatest tv's, I want the best graphics now. and clearly, sadly to say, PS2 graphics are good, but there not good enough. Take Resident Evil 4 for example, on my tv, you can clearly see the graphical differences between the port and the original, the PS2 is grainy and the hair looks like paper, on the other hand, the GC version looks real, bright, graphicaly 3d environments seen more clearly on GC also. I guess I am a constant console war reviewer though.
All in all, the Xbox 360 has the greatest graphics right now, and with my television, it's very worth while to get one. Especially when the graphics of my PS2 look extremely outdated compared to other consoles.
