[quote]Just out of curiosity, did those games also throttle XP gains while selling XP boosters in their stores?[/quote] Probably not, but 1 requires you to literally purchase things just to reach the equivalent of max level. At least 2 of them literally give you an advantage over other players in pvp. 1 of them has actual characters that you pay to unlock and can be used in pvp (I never played it so I can't say if those characters are better than the rest, but either way, is that fair?) 2 of the other ones also took away capabilities that players had to expand the game, and are in turn selling content that uses those capabilities. The others have items that can literally only be purchased with money. Not even a chance at getting those items 3 times a week.
