Since the Novakids specialize in guns, there should be another race that specializes in wands and staves! They have to be lizard people. They just have to be. Their cultural style could be Ancient Greek, with a little hi-tech mixed in. Their structures and towns would be made of marble pillars and pantheons and stuff. They would definitely be smart, but probably not as smart as the Apex. They would essentially be Space Argonians. The hostile ones could have labyrinth dungeons similar to Level 4 (Sewer) from Blaster Master, with a shield generator so you can't cheat. I'm no spriter, so I can't do the envisioned race justice in picture form. Their armor would have Spartan helmets and such, and would eventually start having wings in later tiers. The reason they don't have a key is that back in those times, they wanted to be left alone and didn't want any part of what the Ancients were planning. You're doing so well with "SPAAAAAACE Magic!" that you should add a specializing race!
I like the idea, I really do and kinda wish this was a suggestion much sooner so Chucklefish might actually think about it. Sadly with 1.0 so close and the story more or less decided I don't think they will be adding anymore playable races and if they do they already made whatever they are going to add. Would be a great idea for a mod though.
I have this one feeling that the avians are the most fitting wizard race, with their resonating crystal-based technology. Altrough these seem nice, too.
Chucklefish hadn't improved technomagic until recently. Now, the weapons are good enough to have their own specialists.
