I agree with Valg, there's a big distinction between "Completely free", and "You can pay to get donation items with real life money".

Personally, I feel they should still put Free but Commercial, as that is exactly what it is..

A completely free game would be a game where there is no money involved at all, there are no items purchasable by money, there is no money involved in the game through any manner. Well, I'm just a small mud owner, so don't bog me down, it's just my 2 cents worth.
