Thank you guys for the feedback, it's awesome seeing you reply to all the posts here.
I'm glad to hear that you guys are playing around with a synchronous mode! It would certainly make sitting down to play the game feel much more like an event to sink time into.
After making my comment, I continued to play the game as intended. I realized after giving my feedback that I have actually never played any asynchronous games on the PC before (at least, not that I can remember) and I feel that time spent with the current system has given me some perspective. I still stand by my comment that a synchronous mode would be awesome, but I've come to appreciate the asynchronous play style as well.
I find myself sitting at work, still thinking about the last move I made. I check my email constantly to see if any of my opponents have played their turn. Once I get a notification, I try to analyze the game board from memory and think about what they could have done to get the upper hand. When 7|8 PM rolls around, I'm excited to sit down and take my next turn. In other words, I've come to appreciate the asynchronous mode after being made to play the game that way.
You guys have really outdone yourselves; this is a very good game. The only reason I haven't referred my friends to come buy a copy is because there aren't any left! Keep doing what you're doing and there will be no need to worry about having enough players to go around.
P.S. Tim: I am a software developer by day, game developer by night, and really appreciate the amount of work a game like this must have taken. I get that you're busy with this and everything else going on, but I've been itching to pick your brain about game development in general (mainly things such as your workflow, best practices, advice, etc.). You've really constructed a master piece here, I'm excited that I get to be standing on the ground floor of this project.
