I think the game is coming together, actually. But I've played every version, so all the confusing parts of the tech are something I've gone over repeatedly. (They've also been in the process of breaking/repairing the tech tree since release.)
I think the game is starting to have some internal consistency now. Of course, that will go to taste. I still don't know if I'll recommend it after the 1.1 patch.
Basically, if you're the kind of gamer that enjoys the sensation of a game as much as the mechanics, I think Elemental is a good buy. I do look with pride at my massive, world-spanning empire, and I enjoy exploring each new randomly generated world and making tactical decisions about what to do next. I enjoy figuring out what I'll call my cities, my children, my units.
Unfortunately, the game doesn't carry you much past the "customize it and play it my way" interest. The mechanics break down in several places leaving you with not as fun options. The AI, which really should be the thing that drives game play, is fairly passive right now as Frogboy continues to work on it. (And he's done working on it until after 1.1).
So honestly, whether or not Elemental works for you is going to be based on: your previous irritation with them and your level of expectations going in. I've managed to get over some of my annoyance with Stardock, mainly because I see Derek Paxton working his ass off to get the game as close to complete for 1.1 as it can be. The guy has been working every single day for the last two weeks, and they've been putting out a patch everyday, even over the weekends. They're trying to solve as many issues as they can for the 1.1 release, so they can have the time and the ability to continue making the game better in the 1,000s of ways it needs to be to really meet fan expectations.
