I had several problems with this game, not glitches of course, just little things that alone are but minor annoyances, but together make an annoying game.
1. The cityscape is already in the back ground. How that is possible since your city doesn't even exist technically, until you build your first residential area.
2. The pricing of the buildings made little sense, I have a hard time believing that it is cheaper to build a barracks underground, as opposed to building a small town above it.
3. The units I really have no problem with, with the exception as to when the medic is available. I don't think any self respecting military would develope machine guns before having medics available to keep their soldiers alive.
4. Controling the troops seems like a waste of time on the part of the player, especially since making sure that you actually have built the building you were hoping to actually got built. There is just too much micro management for the troops, it would make sense that the soldiers would attack the enemy that is attacking their city, instead they just hang around like they are on coffee break until further notice. What I'm hammering at is that the units need better AI.
For right now that is about all I can think of, and I hope you either make another one, adding these changes, or put out a patch for this one. When you do I look forward to playing this game again.
