It speaks volumes that the ES link, the first time I tried it, was broken.
I think ES had some good ideas going for it, but the execution failed somewhere along the way. That said, they're still in beta (like everyone else), so I'm willing to give them another shot if they clean things up a bit. It's hard to even say what was not so hot about the game, but it just didn't feel--I don't know. Finished? Thought through?
