Anyone use Yahoo!'s Games on Demand?

Basically, you pay $X/mo. and get unlimited access to a certain number of games. It doesn’t appear that the games are streamed (given the ridiculous download sizes), but I’m still wondering if there are potential issues with running the games.

Of course, now that they’ve got a free trial, I suppose I should just see for myself. But I seriously don’t need another distraction…

Also, what’s a better game: Rise of Nations, Age of Empires II or Civilization III?

I haven’t tried Games on Demand, but I’d vote for Civ III, AOE II, and RON in that order…
