had the notion for a pokemon game on the wii, where the wii game itself is just an interface client, up to ten DSes with a pokemon game inserted simultaneously connect to downloadplay the client (possibly from within the 'World' menu of the pokemon games to speed loading), which then connects them up for a multiplayer Realtime Strategy brawlfest with their currently saved team, control system simiilar to Revenant Wings as the most recent version of the system i'm thinking of that i've played.
What the TV (or ideally, 2 TVs) connected to the Wii would be doing would be between two modes (switching if one screen, one for each with two).
1: birdseye tactical overmap. 2: LucasCam filter swinging a point of view over "dramatic events".. which it would be easy enough to program a filter for 'drama' triggers of various tiers of priority to determine where to swing the camera to. Hell, Empire At War did it easily enough, which is why i called it LucasCam

i don't see there as being much single player content to it if any, if only because writing an AI to realtime any of the various combinations of pokesets would be prohibitive, which would mean rigidly scripted enemy encounters with tailored AIs for their individual configurations. sod that for a joke. Be much better as a party game.
one other notion tidbit was a 'tournament mode' for conventions and such where an appropriately powerful wifi broadcaster could cover the convention grounds, and you could preregister (by friendcode, my goodness, every DS -does- have a unique ID, doesn't it?

) however many people wanted to participate, have the thing random-allocate a tournament table and actually have it poke people's sleep-moding DSes to ask if they want to take their turn wherever they are on the grounds, with option of "no", "i'm coming, dammit" (give them a few minutes to get closer, i'd say starts a timer after which if more than half are "ready now" they can override remaining "i'm comings" and boot them back to the pool) and "ready now" to start.
it's not QUITE as enticing as if they made an eevee-scratch fever game with demented social-sim aspects for the option of building your team without pokeballs, but hot damn i'd play it
