Star Trek Telepaths
Given that most telepaths in Star Trek seem to have their telepathic powers get weaker over distance,most (but not all ) ST telepaths should probably buy Telepathy with the Reduced By Range Limitation (especially Vulcans).
Also, telepaths should have an even more limited selection of powers than normaL: i.e. most telepaths should be limited to purchaing Telepathy and Mind Scan.
