I agree with this. I use Steam for other games but I don't think it quite works with Civ. I do like the absolute freedom with mods that we had with Civ IV and I don't think V gives us that freedom considering everything is attached to Steam(Works). For everyone against something, there'll be someone for it I know. The fact that I use Steam for other games means I don't completely disagree with the model that Steam provides. However, for Civilization, I'd prefer it to be completely optional to tie it into Steam.
