Another kinda random thought: I had complained that the Vorlons and Shadows were too powerful, but after playing another couple of 300+ turn games, I have decided that y'all were right and I was wrong!
In the latest game, as the Centauri, I fought a losing war along with my allies the Minbari against the Vorlons. Each of us lost about three systems (mine were just wiped out, but the Minbari system closest to the Vorlons was actually invaded and captured).
Then the Vorlons left us alone except for intel attacks. It forced me to invest heavily in intel facilities, but that is all to the good. After leaving a big buffer zone around the Vorlons (who waged war on every single species they encountered, BTW, including a takeover of the Gaim), I was able to procede with my plans.
In short, it felt about right.
In the other game, as the Minbari, I just watched as the Vorlons smoked first the Centauri, then the Narn, systems within four systems of the Vorlon Homeworld. Of course, they DoW'ed me as soon as they encountered me, but I left them alone and they didn't bother me (much - intel attacks again, but much less strong).
Again, it felt about right. It was kinda fun sending in scouts who got to watch my allies get toasted and then run for home (only to come back later and find empty systems).
Planet killers seem like a waste of time for a race that has Heavy Lightning Guns, though!
I still like the idea of Line of Sight (20-range) telepath attacks rather than the short-ranged ones in the game as is, but that is another story, for another day, as Emperor londo liked to say.
