I have several d20 sci-fi rules: d20 M+F, Traveller20, Bulldogs!, Star-Wars d20, and Dragonstar. I think that both d20 M/F and Traveller20 would fit for Transhuman Space (that I have too). Then its a matter of personnal taste between the two games. I think d20 M/F would be easier, since it has rules for biodroids and customizable equipment, which T20 doesn't have.johnnype said:I see d20 sci-fi rules as the holy grail of gaming and have yet to find any that could accurately depict Transhuman Space but with D20 rules. What would you use?
