Just because PS2 has Metal Gear Solid 2 (which I'm in the middle of, as we speak) doesn't make it a good console system. The PS2 has a very weak line-up thus far (not counting the PSX games) and has yet to pull something impressive.
PS lost the rights to make any more Resident Evil games to the Gamecube... Final Fantasy X? God no, it looks like a Final Fantasy VIII remix... The creator of the Metal Gear series said that MGS2 is the end of the series, but there will be at least one spin-off game (I'm not holding my breath either)... Throw in one or two rather decent games like Star Wars: Starfighter and maybe even the Armored Core games and thats all you got: a bunch of maybes.
The Dreamcast, though its dying quickly and painlessly, has a spectacular line-up as it fades out. Especially in the fighting games catagory.
The X-Box is being heckeled by almost every third-party developer. They see it as nothing new and nothing thats being done for it is spectacular. Yes, that includes Halo.
The Gamecube seems to hold a lot of promise. I played Rogue Squadron 2 with wide eyes and a salivating mouth at my local Circuit City. Luigi's Mansion was rather blah, but RS2? Wow.
For some reason, whenever I look at my PS2 now, all I see is an Atari Jaguar, with MGS2 as "Aliens vs Predator". Well, at least this one plays DVD movies...
