I wasn’t concerned about the existence of ersatz Romans, but rather, if they were or were not presented in bigoted terms and imagery.There are wrsatz Romans in other products.
I can't recall the art that much either way as it's been to long.
I remember PCs raising an army and invading Thyatis and winning a few battles with 4000 troops.
Struggling to remember the name of said product but the Emperor's name was Thincol and he was having an affair with an immortal named Vanya.
This was 1995 or so perhaps.
Because the product in question clearly used RW bigotry as a foundation of how certain cultures were depicted, any complaints of ripping/riffing off other civilizations loses strength if those other cultures are not similarly denigrated.
