I'm a big fan of the game, but occasionally our playthroughs have become bogged down by certain variants. I'm curious what variants and/or house rules you people really like, as I want to avoid this problem in the future. Lets discuss our favorite/least favorite of them!
1) I love using Space Mines - it's a nice defensive touch without adding a complex new mechanic.
2) The Tribes of Yrril. Banned.
