ah poopie, forgot about melchior.
And ty for the link, STILL I got some complaints and restrictions.... since the link actually provides some info on how things are restricted:
Humans are mostly restricted to only being able to talk to each other using telepathic communication, there where the beastlords from FoT but it seems they possessed some kind of telepathic dominance over lesser creatures. F3 can just go f**k itself with its weird story >,> (solly for ugly language, I actually like f3 but that quest was just a bit wtf)
Super Mutants do have some heavier arsenal when it comes to this area but there are like... not many... so if super mutants are a playable race psionic powers shouldn't be a norm. (I'll bring up my: becoming a mutant idea. here too)
What if you have a choice of becoming a super mutant, you can be dipped in FEV but there is a chance of your character permanently dying or he may survive but he will loose most of his intelligence BUT there is a very very very small chance of him becoming a really smart super mutant and with becoming a smart super mutant they can be given new perks, like psionic powers. (and only mid to high lvl characters may do the "becoming a super mutant" quest.
