MMORPGs are alright, but the problem is you can't play them forever (at least with PEOPLE). Sure, you know that a Zod is worth 3 Sojs, but after a certain amount of time, or a sequel for that matter, who will play it, rendering all your stuff near useless? (DI got overrun by hackers a long time ago, and DII has maphackers and runbots to get stuff they want on ladder). People will dish out money for this stuff, even real, cold hard green stuff (not vegetables) with dead presidents on it (except Ben Franklin), just so they can get ahead.

Not to say they are not fun or worth it (sometimes); that is not the point at all. It doesn't ruin the whole scheme, but it does mean that FFXI won't matter by the time FFXV comes out. I'd be surprised that people will even remember/consider it a part of the primary franchise. It is nice to make friends and actually do stuff with other people, but if you can't do so in REAL LIFE, perhaps there is a small matter you may have to attend to.

Even WoW will suffer the same fate. Well, just MY opinion. We will just have to wait 10 years.
