Opinions: Which version of D&D for Pokemon-like game?
I have an idea for a tongue-in-cheek D&D campaign where the players travel from arena to arena with monsters inside of magical spheres which they use to combat other guilds for badges and prestige. The idea would be that they can summon a monster of their CR or lower, and if they succeed at a skill roll they can command it, otherwise it wanders off, attacks as random, or turns on its owner until dispelled.
Advice on the best version of D&D to run this in? My initial thought is 4th Edition, since that's the most cinematic and action-y, but would love to hear from others.
As a side bar, I'm not interested in any other system than D&D, as there will also be other elements included, so please, no mention of Savage Worlds, FATE, Palladium, etc. I know they all have their flair, but this will be a D&D game.
