Playstation2: Excellent Library of games, tons of developer support, comfortable controller, wide array of connectivity thanks to USB. The best system for the money right now, IMO. Could use a price drop, solid online plans, and better graphics though.
GameCube: A handful of quality titles with a few more leaking out at sporatic and distant intervals. If you\'re looking for instant gaming gratification, the Gamecube most likely won\'t accomodate at this time. They\'re set up to have some excellent titles in the future though. Low price point is a great incentive, but lack online plans as of yet.
Xbox: Promise. A handful of great and original games, tons of ports which may end up making a "Me Too" console if Microsoft isn\'t careful. The most powerful hardware wise, and comes standard with a harddrive which is a very nice - if underused- feature. Solid online plans, which unfortunately cut off most of their customer base from online play since it\'s broadband only. For those who have broadband, the Xbox will probably provide the best online experience this generation. Controller is a bit uncomfortable to most people.
Dreamcast: Yeah, it\'s dead.. but it\'s still outselling the Xbox in Japan. :P It was still a contender in the 128 bit wars, and should still be included in this IMO. Desperately underpowered, but had a ton of great games available for it. Online out of the box through 56k, and still the only console that\'s currently online, but could have made a lot of people happier if the BBA was more widely available. The VMU was an excellent and novel idea, even if they ate some pretty expensive batteries.
