Paying for Planetside

[ChipMHazard]

Quantity would be my guess. It seems like there will be a lot of cosmetic items, and possible booster packs, in the store.
I certainly see your point about how to make sure you keep making a profit over a longer period of time, but it seems to work really well in other free to play games (although a game like LoL does sell booster packs).
I don't really think we need to "worry" that much about SOE making a viable F2P store model since they most certainly have enough experience in making them.
