A few people have been very vocal about the lack of equity and how "unfair" it is.

Personally, I don't really see their point. It's not an investment, it's a purchase... With a slight bit of risk. Some of the higher tiers are collector's items and a part of history, and unavailable otherwise. The lower tiers have the game for less than it will probably retail for.

I personally feel the risk is very low for both this and Wasteland 2, but others feel differently.
