Dangit, I wish some people would just make incredible things like this just for the sake of making them, not for money. Having bonuses that are available to the player over time but can easily be bought with money pretty much ruins the playability of the game. If somebody feels the need to give you money, they can simply donate to you instead of being put off by your buyable bonuses.
