Kingdom Hearts: How to beat Ansem (Robotic Riku) ?

[GrooveMan.exe]

I would rather have a Gaiden game that has all playable characters so far, with each having a decent number of their ingame weaponry (even just giving everyone 5 or 6 weapons each would result in a shit-ton of possible character/equipment combinations). You play out various bits and pieces from the entire plotline, alongside a giant What If mode where you can be whatever character you want in whatever mission, with multiplayer.

Meaning you can do things like the Saix Vs. Sora fight in KH2 - but from Saix's point of view; then go to What If mode and beat up every Heartless Boss from KH1 as a Terra and Luxord team.

Considering KH: Coded and the Data battles from the Final Mix games exist; justifying this in-plotline wouldn't be too difficult either.
