Sonic may be fast, but he also tires. Zero's an android, and if he drains his weapon or life energy stores, he could have it refilled by another and would still keep on going. Just because we play him (Sonic) on a game as the tireless hedgehog he is, this is a "real" battle we're dealing with here, where nobody controls the action and realistically adds up to the tension and drama of who will win against who. We don't use control pads and urge him to go as far as he likes. He's just a hedgehog, could you blame him if he stops to rest for a while? And are there rings involved in the arena?

I was asking if the fight would be fought in 2D or 3D in order to point out some points to be pointed out, with each weaknesses set to another's advantage, and all that. I mean, I was just pointing it out. I didn't mean anything about it...

Life is short.
Let's all grab a BEER~~~!!!
