Finally got enough time in to vote.
0.91 is a significant improvement from E:WOM and I feel things are heading in a general positive direction.
I voted "poor". I think it was close to being "fair", but I often felt that I was working for Stardock rather than having a fun leisure-time activity. The main issues for me were probably pacing, balance, and development.
PACING: While I think the bugs and stability issues I experienced were within the realm of the acceptable for a beta, they did detract somewhat, but my main concerns were pacing. After the early game, I found myself quite often hitting "end turn" without much happening that caught my attention. I should say that I did not feel this is any worse than, say, CivIV BtS, the last iteration of Civilization I played -- I only ever completed one game of that. I found it (Civ) to be quite boring after the end of mid-game. In other words, I found CivIV BTS's pacing to be poor at best, and one of the reasons that game is "not for me", despite its many positive elements. Unlike games such as AoW or HoMM(3), I felt that only a small portion of the turns were meaningful.
BALANCE: I often felt that there were too many no-brainers, and hence lack of meaningful choices for me to make. Once I figured out how to make Champions, I could ignore the often moot task of making units, and using them. I just stomped around with my champions and defeated everything else without ever "choosing".
DEVELOPMENT: I did not enjoy managing my cities, and had to think of Derek's "Go Big or Go Home": why not git rid of them (as some 4X games have done)? Be that as it may, I did not yet feel much connection to my cities, differentiation amongst them, or, after a while, even understand why I would need them after founding my original city. Owning vast tracts of land did not seem to be necessary, and I stomped everyone with my sovereign anyhow. Additionally, I found that I could ignore most of the tasks of research, since I felt that what I was getting was coming too late, or had too little effect, to make much of a difference. Again, I mostly ignored making armies, and I am sure I am missing out, and in fact feel that I am, but I felt there was not enough motivation to invest in them.
Overall, I found the AI to be suboptimally idiosyncratic, and while I realize I was playing on default (easy?) level, it did not seem to be making wise decisions.
I want to say that I believe many of these issues can be addressed before the autumn (possible release date), and I am cautiously optimistic about this product becoming "good" or even better in the future.
