i've also grabbed the xbox and cube and have to admit that the cube's left a bad taste in my mouth...reminiscent of the n64 launch.
nintendo really dropped the ball with their launch titles. they released at least three stellar titles within the first month of the system's release but the problem with each of those games is that they can easily be completed on a rainy sunday.
once some of the larger first party releases come out, the cube should pick up some steam, but right now it looks like the xbox is going to distance itself from the cube after march...jet set radio future, wreckless, gunvalkyrie, etc. but rare's right, the ps2 is holding up amazingly well and with maximo and state of emergency coming out for it next month, it should be another great month of releases for it.
