To be honest, I think the PAL title for River City Ransom is a good building block for various games; "Street Gangs".
Street Gangs Rivals
Street Gangs Soccer
Street Gangs Hockey
Maybe go all over the franchise and do Crash N' The Boys -- and throw in some subtle Scott Pilgrim love while you're at it, 'cause I say so.
Could of course also try to build on the River City name, since that's totally the one most people associate with the franchise -- other than maybe anyone who sees all games as "those other games that looks just like Nintendo World Cup".
Maybe it's the non-native speaker in me that just finds "Hot-blooded" to sound a bit strange/stupid. In general, I like to consider most things expendable as long as a suitable alternative can be found and its usage is thought through.
Now, just to throw out silly stuff from my system;
Jersey Shore - The Game - This time they're Samurai
"Douchebags -> Douchebag Soccer -> Feudal Douchebags"
Youth in Revolt
