Here are some thoughts about local multiplayer and the AI.
It was already announced that SC will have multiplayer capability over the internet. Will it have local multiplayer as well? I hope so, because it was fun to battle my friends in person. I would be very disappointed if I couldn't humiliate and trash talk my friends locally. That was part of the draw of SuperMelee.
One other thing that might be fun would be to have the ability to have the option of local co-op in the campaign itself. Since the engine supports multiple ship combat, why not let us have 2v2 combat? Me and my friend vs two AI pilots?
AI vs AI:
Sometimes, it is more fun to watch than to play. You can learn a great deal by watching two Awesome Cyborg AIs fight. It was how I figured out how to use certain ships effectively. (Watching an AI battle between a Supox and a Chmrr was fantastic, even though the Supox was destined to lose most of the time.)
