1 Question , This is the first I have heard of steam. My question is simply , what games distributed on steam have a recurring monthly charge?
HiTech
As far as I know, Everquest 1 and 2, Aion, Champions Online, Eve Online, Lineage I and II, Warhammer Online, and Pirates of the Burning Sea (at least that I remember).
The thing these all have in common is an upfront price to buy the game, something AH has never had that I remember. I'd suspect there's licensing and hosting fees to valve, but the backend (i.e. Servers, network) is still controlled by the developer.
Also, for those with Steam that would like to still use your friends list and stuff, you can actually ADD Aces High II to the Steam games list (click Games -> Add non-Steam game), and as far as I've been able to tell, works fine for me with my Vista 64 system, and the "Shift Tab" Steam overlay works as well.
