i got psc ps2(jp) and akso Dreamcast
the later 2 have same graphic i think
the only different is the amount of graphic that ps2 can process at once is way more tha DC. (same quality but different quantity u could say)
to be honest.. wait till it have more good games..
i look at my dc, it does not have much fun game really... but psx.. even its graphic look like **** now.. but it have alot of fun games.
so wait for a bit and see if PS2 are gogin to have lot of good games or not..
(for now i only have fifa 2k by EA sports and tecken tag battle for my ps2)
