I like it! Just finished a v0.4.8C Beginner game in Arch -- first 3-4 games I starved almost immediately. This last one, once I got going, went well. :)
The auto-population growth definitely make it different from ~AoE games. End up trying to race Military units creation before the civilians take up the additional population cap. :)
One annoyance I do not miss from those games is having to re-seed farms.
Would like to see more upgrades for the various buildings/units, and larger tech tree, with pre-reqs. I'm sure you already have all this on your list.
Great little game so far, can't wait to see what it becomes. Thanks for adding Linux support early-on.
