Yea I'm pretty sure Ridley is worth being playable

If anyone from the Metroid series would join, it would be him. His history runs deep with Samus, killing her parents, scarring her for life, and he is in most Metroid games (all but Metroid 2, Prime 2 and Hunters)

Besides just because an element isn't present in a demo version of the game (Pyrosphere) doesn't mean it isn't finished at that time necessarily, the developers pick and choose most things, and I believe Pyrosphere was indeed finished.

Also there's probably no need to be so pessimistic. All you have going for you is your interpretation of an indirect nod, while I bring some facts.
