My opinion is... SEGA SUCKS (damn, I haven't said that in a while)
They release any ol crap and it get's hyped up WAY out of proportion because of name recognition. This year, besides Virtual Fighter 4 and Monkey Balls, I haven't seen Sega make one game that is above average (and not a DC port).
I think all these crap releases will soon hurt thier name... which is good as far as I'm concerned. Right now, they are no better than EA, even in non-sports games.
Sonic adventure 3 should save thier name... but until then we have Shenume 2, PSO, Sonic Mega Collection, and Panzer Dragon. (

I'm pretty sure the ol dreamcast.ign.com would have given every game they released over a 9.0 just becauseit's Sega.
