But just two weeks ago I had a burst of inspiration; they always seem to come when I'm diligently working on something else. Fleshing out this idea in Illustrator led to me meshing around with some effects and led to something completely different.
The character select screen would function such that players select their character from the jumbrotron in the center. When your cursor is over a character, your respective banner and the model underneath are changed to that character. Actually selecting the character causes him/her to do a little animation and play one of their voice clips. I'm also toying around with the idea of the characters randomly performing attacks before they're selected so players can get a sneak peek of their moveset.
Considering this was all done in Maya, the plan would be to polish these assets, bring them into Unity, and animate them there.
