If you like Pandemic, Shadows over Camelot, or Lord of the Rings (Knezia), you'll love Flash Point. It is a coop fire fighting rescue game with all players working together.
It borrows a lot from Pandemic, but personally, I think it does a better job at keeping all players involved, unlike Pandemic, which suffers when more experienced players end up telling everyone what to do, and it becomes a play by proxy game. Flashpoint involves all players continuously. Two games (Family and Advanced) and several skill levels, not to mention cheap expansions ($22 each at some suppliers), will keep you coming back for more.
