My thoughts:

First of all, I don't want to jump the gun too much. I'd really like to finish out the WAR RP.

What is the threshold for "enough interest" in order to begin planning a Team RP?
12-16 people seems fair.

What is the entrance requirement for a team? How many teams will there be?
I'm liking the 4x2... system we're talking about right now.

Modern technological level or futuristic?
I kind of want to go futuristic.

Will it be set on the Pokemon-world/Maridia or on a planet(s) of our own creation?
What if we had each team create and control an entire dimension? So one team could be a future dimension, one could be a magic dimension, one could be the Pokemon dimension... etc so that everyone sort of gets to do what they want and we can do something of a scale not yet done.

Should project lists be re-introduced?
No.

Do we need to have Pokemon in the RP?
See above. I'm just getting a little tired of the little critters, that's all.
