I really like RPs, but I'm just not sure where I'll be come a few months from now. But in any case, I could toss in my few cents here.

What is the threshold for "enough interest" in order to begin planning a Team RP?

I would say at least ten people and two teams as the bare bones minimum. Given, the more, the merrier.

What is the entrance requirement for a team? How many teams will there be?

I agree with Bron, I would say a four member minimum. As for number of teams, anything between 2-8 is feasible, and that's a pretty wide area to work with, I feel.

Modern technological level or futuristic?

This is a toughie. I'm leaning a bit more toward futuristic. Because... well... laser explosions!

Will it be set on the Pokemon-world/Maridia or on a planet(s) of our own creation?

World-building gets tricky and the issue there is it often feels smaller than working with the Pokémon world as is. It really depends on what you're going for, though.

Should project lists be re-introduced?

We don't really need them. I'd be okay either way, though.

Do we need to have Pokémon in the RP?

Nah, we don't need them, but if you take them out, definitely consider having something else to fill in the void that's going to be there when no one has the critters to summon. That could be anything between magic, superpowers, abilities, and whatnot. Races has always been kind of a weird area here though. We've tried it in the past and got mixed results, so I'm not sure.

And some other considerations include:

For one, a Team RP with the setting style of Wreck-It-Ralph, I feel, would be awesome. If you haven't seen Wreck-It-Ralph, shut off your bloody computer/phone IMMEDIATELY and SEE IT NOW. Just kidding, but seriously, it's an epic movie, easily one of my favorites. But in a sense, it's a setting where there's an arcade, multiple games are connected via a surge which acts like a grand central station that allows characters from one game to cross into others.

In this scenario, each team would represent their own video game (one that's made up), and the objective there would be to defend their own unique game world, but then try to sabotage the others. Meanwhile, there could be something else going on, such as a computer virus or something that's messing with game code and causing mishaps to happen.

The other idea I've always wanted to try is a Kung-Fu Panda style RP where all the characters are anthropomorphic characters using Chinese or Japanese weaponry and fighting styles in a Feudal China/Japan setting. Incorporate some magic and/or special abilities/powers and I think it could be the recipe for a pretty interesting and fun RP.


So yeah, there's my input.
