Yea. I really like that blue set, but make a color set for all, that way, when people start donating, you make more money, because they may want to mix and match, not only that, the more small shit you add, the more that players want, the more they will buy. If they keep buying, you keep making, just like IJJI, you get more money. Eventually you will have a good set/list and alot of people will hear about it. Keep making donates, don't stop. the second you stop making donates, once everyone that can buy, has, you won't get any more revenue.
In essence
Donates = money
money = server fame
server fame = players
players = buy donates.
see the vicious circle?
