I've always enjoyed games that had a huge variety of enemies to kill. This would probably be one of those unreasonable or unrealistic ideas but this is just something I'd like to see in SC:O
I'd like to see a random monster appear in some star systems, something like Master of Orion where you'd have a space eel, dragon or some kind of active derelict precursor defense platform that guards the system.
I'm assuming there's already going to be a large variety of different planetary aliens to kill with your planet lander so I think it would add a little bit more fun if you randomly encounter a scaled up version of those aliens in space. A legendary beast that protects the star system!
What are your thoughts on this?
