There's a thread around here somewhere where I rant obsessively about my hatred for it and Alec mocks me, hence the above comment. I won't sully another thread with my rage, but I find Steam to be a horrible ideological blunder that will be nothing but bad for consumers in the long run (hell, it's bad for them even now). Still, it's hard to say that Aquaria shouldn't be on there. The simple absence of it isn't going to hurt Steam any, much as I'd like to see Valve's efforts there crumble into dust, and having the game available there would most certainly give it more exposure and greater potential for sales. Sure, it'd be great if this could be achieved without Steam, but the number of people that use the service is staggering. Even with a great marketing campaign and lots of money to throw at it, not having a presence there is probably illogical. That's why you can find practically every game under the sun being sold there.
Still, I think the guys would perhaps do well in the short term to get it on Stardock Central, Stardock's Steam-like distribution program (that has none of the things that make Steam so rotten, at least in my experience with it). It seems like most of the products there are more in line with Aquaria's indy-friendly audience. Of course, I don't think the game should be limited to that audience alone, obviously, so it's a suggestion of only limited use, I guess. And I know nothing about what Stardock takes from sales there, etc. But it might be an easier initial step to take.
