JSRF wasn't a flop. If you like the original, the sequel ruled. If you didn't, it's not your game.
And Amped sucked, big time. So did a lot of the "amazing" launch Xbox lineup. Remember all the hype surrounding Shrek?

Can't name a DOA game that was great. DOA3 was even said to be a graphically beautiful DOA2:HC )which sucked) but Xbox fans just didn't believe it.
Anywho, it has some nice sports games, not much else I care for. I like my Gamecube far better, cause it still has much better games.
Xbox has a good future, but this fall still belongs to GC. Xbox will be online, Xbox will definetly recieve the most online support. So if you want to go online in a wide variety of titles, get an Xbox. Because Xbox 2 will likely change Microsoft's online gaming plans for the worse.
