United Law was a futuristic campaign designed and run by one of the Romford Gaming Group’s original DMs.
He created it from a mishmash of his favourite sources so there were elements of Star Wars, Star Trek, Andromeda, Stargate. Although he used the D20 Modern ruleset as his base, each addition that he tried to include ended up with a strange set of rules that broke the D20 rules in most cases.
An example were the Force Powers he imported from Star Wars – he tried to make it so that they activate on a low roll of a D12 or D8 rather than re-using the SFX rules from D20 Modern.
Needless to say, it didn’t last very long and we moved onto Exalted after that.
