How can any one be the best? All have advantages & disadvantages over eachother in both hardware and software.
Oh, also...
...Sega Genesis...had VERY few impressive Games Graphically
You...you're joking right? I'm about to be that guy.
We've got:
Alien Soldier
Ranger-X
Red Zone
Gunstar Heroes
Thunder Force IV
Mega Turrican
Shinobi III
Bio Hazard Battle
Virtua Racing
Street Racer
Contra: Hard Corps
Zero Tolerance (plays better than any other unassisted-16-bit FPS)
Duke Nukem 3D
Earthworm Jim (two of em)
Yu-Yu Hakusho Makyou Toitsusen
Castlevania Bloodlines
Star Cruiser
Beyond Oasis
Skitchin'
Maybe even more. If you care to make a similar list for the other two systems, then be my guest.
Also, I've decided that anyone who says the Genesis has shitty sound & advocates for the other systems is an stoopid head. Sure some Genesis games sound like Casio farts, but others sound like arcade perfection. Some SNES games sound like redbook audio...others sound like really low-quality MIDIs, which can also occasionally be likened to the unmistakable sound of flatulence. The PCE in the wrong hands produces shrill, master system style PSG tones that have no place on 16-bit hardware & honestly, rarely sufficed on 8-bit IMHO.
And I'm done. Sorry I'm an insufferable fanboy, but I'm more than willing to be proven wrong.
