I can sort of understand where you're coming from but really PS3 and PC are two different platforms. While it'd be awesome to get both at once, the upside to having to buy both is that you'll get 60 days of free play time. Plus, you don't have to pay a separate subscription for both platforms. Look at DCUO from Sony Online Entertainment. I've got it for both PC and my PS3 yet I need a subscription for each platform and each platform is it's own game.

As for needing to buy expansions more than once even though you have multiple players in the same house... Sorry but I don't get how you can see that as an issue. That'd be no different than being upset that you and your husband had to buy the game twice to start off with. I don't know of any MMO that doesn't work that way because it would be far, far too easy to game the system if you could log in the same account multiple times at once.
