I look for some sort of robotic race for a 4X game. I want them to be at least a bit unusual, they should be hostile and dangerous, but they can't have a goal of galactic conquest. Generally, they could/should have some weird patterns of behaviour (like not taking some planets, being limited to a part of space, etc).
It's an NPC race so don't worry with victory conditions and things like that (they just live in the same galaxy the player lives).
I look for:
- overall description who they are and how they behave (and possibly why) [on strategic level]
- it's less important but if you have some gameplay mechanic (what they attack and why) that would fit them, post
