I'm inclined to agree with Aeana really, it's a good value if you play a lot... but when you don't it's a terrible waste, and certainly you won't do it on multiple games because why do that when you could just focus on the one and get your money's worth? Which is actually something of a hidden third angle: people are already paying for WoW, or maybe something else of their choice, and as such have no desire to lump on a second subscription. It's probably also the reason why WoW's success can't be replicated, at least by a WoW clone: that market's tapped, you need to find another. And honestly, I wouldn't be surprised if DQX found that market, but only in Japan. We'll see what happens in the US, maybe Nintendo can work their magic and find this not-WoW(/FFXI) crowd, certainly I'm more eager to for this than anything else.
Similarly, I feel kinda bad when I squander months of Netflix, but at least I feel like I'm keeping the door open to broaden my film literacy as it were, not to mention streaming gets plenty of use. Don't feel I could use similar rationale for an MMO, they can be nightmarish time sinks.
