Since this is Crime City, do you know what a Hasa is? That's right it's a Pig that doesn't Fly Strait! This game is a flash in the pan. It will not LAST! The developers got fat and lazy with the sale of this game. Instead of improving the game, they decided to Sell POWER. The Bank Buster and the Hit and Run car, started the death of this game and they know it. Since these Modifiers selling Power is the number one goal of this game. This game is way out of Balance and can never get it back. Gree know's this, they will care less and less about this game as the money dries up. Boycotts will only speed this up.
The Three things that will keep this game going is
1. raise the top level and give players 10 more skill points every ten levels.
2. Allow for more expansions 30 is not enough
3. after level 100 all defense buildings should give stated defense values.
Gree if you are going to be Dumb enough to sell power, then give Defense away for Free, return at least some Balance!
