if not for AM2, Sonic Team (the original guys from sonic adventure 1 and before that time), and Team Andromeda there would be no true innovations in the gaming industry. this credit includes Nintendo' s efforts (gotta give mario and zelda props for what they did).
no one seems to want to give true credit where its due. before Tekken there was virtua fighter.
before Ridge Racer, there was virtua racing and Daytona
before Time Crises there was Virtua Cop
before GTA 3 there was Shenmue (which is more artistically inspiring and culturly motivating than GTA will ever be)
before Crash Bandicoot, ratchet and clank, and jak and dexter, there was sonic the hedghog.
before ANY 3d playstation shooters, there was panzers dragoon (correct me on this)
SEGA had the first 128bit console, gave us a VMU to show innovation for gamers, put the console world online with seganet (and even on the saturn with netlink), and if not for the TurboCD, and SEGA CD, we' d probably be still playing with cartridges, or some inhanced version of them.
Resident Evil 4 didnt create the quick timing interactive features...common guys. S H E N M U E!!! (sorry, i literally had a debate with some guys over this)
and before i shut up, last but not least...i popped in shenmue on my dreamcast about 3 days ago....and it still looks waaay better than 95% of our modern consoles best efforts.
ok, im done.
