Skasi there are already plenty of ridiculous awards that can "encourage" bad behavior. Someone can build a giant tower to get Legendary Landscaper.
Let's just say that there are categories. Some awards indicate generally good behavior. Some are neutral and are just for fun (above mentioned). One is definitely negative (friendly fire).
More awards are fine at this point, but I kind of want to increase the difficulty of awards so they appear less often, which makes them more special. Right now every giant game ends with like 10 awards.
