(At the same time that probably makes it a good choice for a game implementation)
Thing is that for all my examples above I had a "good" reason to implement that specific game:
1. Dominion (shortly after it came out) To evaluate strategies to best my friends (obviously). 2. Eclipse Has a nice rock-paper-scissors type of ship combat, where you can counter every enemy build (if you have enough time and resources). Calculating the odds of winning would be interesting. 3. Homeworlds Seems to be a very fascinating game. But without any players to compete with [0] ... AI to the rescue ;-)
[0] I am aware of SDG where I could play online, but that site is in decay mode. Getting an account involved mailing the maintainer and those times I tried to start a game no players showed up.
