Well... nice that you took some responsibility, but oddly, you focused almost entirely on the crashing issues, and little or not at all on the UI and balance issues. I believe you said something like "didn't live up to customer expectations".
From this, I assume that having a UI where a lone sov comes into my territory when we are at war and destroys his entire empire when I attack him with a small stack is up to YOUR expectations.
Ironically, I had little or no problems with any actually released version of elemental as far as crashing. Yes, archery didn't work at all for me, due to the "not enough actions" issue, but the game played solidly.
For me, the game was, and is, still a bust due to it providing me zero challenge on any difficulty level, due to poor balance of units, extremely poor AI, and such.
I like the game well enough to hope for these things to get drastically improved, and believe that you'll do just that in time.
However, to be perfectly honest, the fact that you skimmead over what I see the biggest issue with Elemental in this mea culpa of yours, makes me feel like it is less a mea culpa, and more of a diversion of responsibility on to the engine problems.
Here's to playing a great elemental by the start of next year! I'm sure it will happen.
