If anyone wants to host Jurassic Park Mafia...here are my ideas. If you like them take them, and you can add more to it. These are just some ideas how to make it interesting and add a different feel to a Mafia game, without being too out there with strange roles or rules.
I was playing around with the idea of each Raptor can pick targets for themselves instead of just the boss. The idea being if a Raptor attacks it has to wait 3-4 days to attack again. (The number gets lower per number of Raptors left in the game.) So if the Mafia wants to do a big hit of 4 people one day...it would mean waiting for 4 days to do another attack. Though this power might be too powerful.
Wild Card Dinosaurs: Wildcard dinosaurs are not on any team, and their goal is to be the last one surviving. If it is Dinosaur vs Dinosaur 1 on 1 the Wild Card will win. Also these dinosaurs actions are the first thing that happens, even changing the vote. The order of Wild card is always Dilophosaurus and then T-Rex.
Dilophosaurus: Each night the dilophosaurus picks one player. That players vote does not count towards the tally and if he has a special ability he can not perform it. If he is Mafia and was going to attack, his attack is cancelled. The Dilophosaurus can break up ties in votes or even create ties.
T-Rex: The big bad T-Rex must be killed twice to be killed. That means either voted off twice, or hit twice or a combination of both. The T-Rex can attack each night. His attack takes first priority and is the first action after the vote. If the vote is a tie, the T-Rex can choose to eat any two characters of his choice and even ignore the vote results.
You notice there is some evil synergy between the Dilophosaurus and T-Rex even though they are not on the same team...evil stuff can happen if they teamed up. Also notice the backstabbing nature of the Dilophosaurus as his actions happen before the vote and the T-Rex right after the vote...so if T-rex is blinded no actions...hmmm...
Since this is only Jurassic Park I think keeping the Dinosaurs limited to the big three from the movie is enough.
Donald Gennaro: The Lawyer: When Donald Gennaro is the target of being killed by hit or vote out he can choose another character to die in his place. This person must be turned in before the day is over...If he is not killed or voted off then nothing happens...but if he is attacked the switch occurs. If Donald accidentally picks a dinosaur as his target he dies but the dinosaurs role is revealed to the game.
Lex and Tim Murphy: They are brother and sister lost in Jurassic Park. They know each others roles...but if one dies they both die. Sucks to be related...I wonder which one tastes better to dinosaurs?
Alan Grant: He can use his expertise in Dinosaurs to Research the roles of players. He can not determine what role a Townie member is...only that they are human. But he can determine which dinosaur is which.
Robert Muldoon: He can hunt and kill dinosaurs...but if he is not careful he might accidentally shoot an innocent person. He actions take priority over Raptors, unless he is the target of the attack...then its "Clever Girl" all over again. Example: Raptor A is killing Lex but Robert Muldoon targets Raptor A then Raptor A is killed. -OR- Raptor A is killing Robert Muldoon and Robert Muldoon is targeting any dinosaur then Raptor A kills Robert Muldoon first.
