I don't think any of this really matters because other than on this forum, I don't speak of the creations in the game with other people and I believe the same applies to most of you. Although it might matter if you talk to yourself while playing the game, which is perfectly normal.
By the way, I pronounce it geneforge as in generations
jeanforge sounds retarded although it is more correct.
I don't know why, but in my head I pronounce rotgroth as roTHgroth. Also rotdhizon sounds like rothdhizen (as in horizon) but now I'm just making me sound like a fool.
