I know that minor races shouldn't play a major role in the game but i find minor races to be very weak.Their role in all my games is doing the role of milking cows if friendly or to be wiped out with a few ships by me or other races.In my opinion the problem is at the root because they can't colonize other planets, so they have always systems with very good planets that they don't colonize.So why don't give them at least the ability to colonize the planets in their star system, it's very stupid that they don't colonize planets in their star system with a PQ of 15-16.It's also stupid that they declare war on me sometimes don't send any ship to attack me and everytime they come back to negotiate a peace treaty giving me the possibility to take some of their money,tech or other resources.
It should be also added an event like "minor races have decided to ally between themselves to count more in the galaxy" or similar.
Resuming:
-i don't think that giving minors the ability to colonize their planets could change a lot in terms of gameplay, they would have only 2-3 planets instead of 1, but allow them to play a bigger role
-minor race AI is a bit stupid and should better take in count their own interests
-an event in which minor races are involved to play a bigger role in galaxy would be really appreciated (don't tell me fundamentalists, or terrorists.I want that dark yor,carinoids plays a bigger role for example)
