I'm jealous of you EBers

[MarcusAureliusAntoninus]

You only need a separate install if you don't want any form of conflict with vanilla or other mods. Since EB uses the mod switch, you can still play vanilla or other mods with limited conflicting data. The only major conflicts are the loadbar and the strat map models (and with the next release, the map reskin).

And welcome to EBism!

I have EB, RTRPE and XGM all on the same install...not one problem

XGM is tits. XGM: Diadochi is out now too, although I have yet to try that one. It's the only mod that I know of with a playable Pergamon.
