I wanted the physical goodies in the CE, and that also included the Mog Cap and Cait Sith Doll Minion. I had everything else already.

I haven't played games with a "cash shop", but I think most of them limit what you can do unless you buy something. Like making you buy guildleve allowances, or monthly rent of inventory space, or primal battle tickets. I don't like that kind of thing.
