I'm thinking there should be some kind of reward for players that support the game by buying points. There could be different V.I.P. levels depending on how much a single players spends on the game, however, I don't think the rewards should be anything substantial (no credits, points, etc) basically just something that would make the game easier without giving the V.I.P. an advantage over a non-V.I.P. player.
One idea for a reward could be warp coordinates. Basically, a player can choose a map and coordinates on that map, and with one click could be instantly transported to that area. Or a V.I.P. could receive a bigger backpack or extra bank allowances. Something of this nature might give some extra incentive for players to support the game.
This being said, I don't think buying PP should count towards V.I.P. services since becoming a PP has it's own rewards (World Build, Item Maker, etc). This could be strictly for buying points thus making buying points even more attractive.
