SSBB: The Games

I want to make not one, but two games based on SSBB.

One: A card game, using the established characters. Sort of risk-VS-reward, some resource management, and just enough luck. Each character has a different deck (all hopefully balanced). There's also a deck for the stage (differing) or maybe just set rules for each stage. Also an item deck. And maybe an "other stuff" deck. 2+ players.

Two: A gamist RPG using new characters. Maybe use some established characters as samples or cameos or something. Not too sure rules wise, but I may end up taking inspiration from GRiM, as I really like what's happening there. I may also use some aspects of the card game, but it'll be an almost completly different game. I'm thinking something based on SSBB's story mode. Sort of dungeon crawling-ish type deal. But I've gotta think of some way to make it interesting, not just a rehash of DnD with funny characters and items.

Any thoughts on either one are welcome.
