Hey,
What does it mather who got the idea? Almost everybody playing gta had the idea of a stunt mode.... So there actually is noone who discovered it...
example: If dracoblue (or mta, doesn't matter actually) stole your ideas... What have Unreal creators, Quake 3 arena etc. etc. stole then? I mean, they all have Capture the Flag or Team Deathmatch...
This isn't flaming, just giving my opinion.. GTAT and MTA:VC both have great things accomplished... Get multiplayer to a game that isn't built for it!
