Yes, both ideas are very good. I would probably end up joining both...
If I had to choose one it really depends whether or not we give the "ancient game" discussed in the Spiralus game thread a chance or not. If we are trying ancient, I would choose "War & Diplomacy". If not, "Isolation Breakout".
I hope we start both games (as well as ancient), so that's three new games for me. Making a total of six. But I think that is the max I can handle
