I agree, but I think the problem is you have the choice between faster turns and more human players.. I like more human players better and still like the game even if the turns come in in 30h-50h. Sure I dont like it but for me its better than play a singelplayer game (where I get my turns in seconds).
I think many AIs are fine, just like you but then they are the spice for me
. The AIs should be just a barrier for humans not real opponents. At least in my view.
Sorry I overread the low ship limit part, sorry.
