What games should I get?

ED is not an RPG. It has an awesome magic system, but that doesn't make it an RPG. An RPG has to have at least one of these factors.

1. Turn-Based Combat
2. Character Improvement Through Experience or Levels
3. Multiple-Person Party Configuration

ED has none of those things. The magic system alone doesn't make it an RPG. It's a psychological thriller/adventure.

But, you're right about Skies of Arcadia Legends. If you like RPGs, KA, buy Skies. It's one of the coolest RPGs I've ever played.
