Hiya. Is there a way to replace the alien brain power need with energy? I've never played aliens before and I just tried one out today, but they feel kind of cheaty with how slowly the brain power depletes and how fast it replenishes. Makes an already easy game too easy, IMO. So I'd like a sim with the usual alien visuals and alien powers, but without the brain power need. Is there some way to do that?

I'm afraid there is not without scripting, no.

What you could do is make an ITUN tuning mod to alter how fast the Restore Brain Power interaction restores the motive. By default it's 50 per cycle but that can be lowered. A bed for example restores energy at 21.33 per cycle. You'll want to change the value in the Output node toward the bottom, the actual not the advertised.
