Finally had a successful test run. It took me a little while to get comfortable with the arrangement, but then the game just flew! I mean, a single game takes less than 10 minutes, it seems. I'm not too surprised, but still! I tried playing with the expansions, but it crashed mid-way through the first age. I'll try again tonight. I think the app auto-reports crashes since it is run through the App test program from Apple. But I could be wrong.
I still am not able to select "Random" for the distribution of wonders, which is a bit annoying, and it doesn't look like the game saves your scores, which would make it much more fun. I would really like to see some medals or achievements built into the solo game, but perhaps there are plans for that in the future.
