What do you think about alternative payment models?
Some players will flame everyone who dares to mention F2P, but then there's also games like Guild Wars, which was ~50$ for each expansion and no monthly cost. I liked the GW model and it was also pretty successfull. EVE has quite a unique model, but i'm not sure how it really works. D&D Online seems to do much better as well after switching to a model based on buying expansions and items.
The reason why I like alternative models is that they allow everyone to progress at their own pace. It's better for casual players in general. I don't really despise item shops either, as long as they're fair - but i guess an item shop for Xyson is out of question, anyway :P
