I had the game just close without any message and exit to the desktop. I'd only been in int a short time, but I noticed that I was being nagged to install the latest adobe reader patch, so I suspect that is what caused Elemental to crash abruptly.
Another error I came across was when I tried to load a save game. It went into the movie as the game was loading, but then just got stuck. thee movie kept playing, finished and then started again. Nothing I could do could get it out of there, so I had to kill the task with task manager. Unfortunately I'm unable to duplicate the bug.
Also a general criticism is that I rend to run out of buildings to build too early. Maybe Im missing something, but I quickly reached a situation where I couldnt build any more housing beacuse of not enough food, and it wouldnt let me build any more food production. The icon for the food building wasn't grayed, it just wasnt there at all, so I guess this is a 1 per city concept, which I think is a horrible idea if I need more and more food. I can understand not being able to build 2 town halls, but not being able to build more food buildings just seems very odd to me.
To be honest I preferred Beta 2 when you had to build lots and lots of gardens, to being limited to 1.
Also, the buildings seem to build a bit too fast compared to the pacing of the rest of the game.
