For me personally its great. Its the only game I can get my partner to play. The rules are streamlined and simple but not dumb or overly complex. Coming from Fallout wasteland warfare which basically no one wants to play. It just takes too long to setup and play a game. Not saying its bad. Its just that games like these can really suffer from the need to have massive armies or overly complex rules its hard to get people to get into it.
Zone wars solved that for me. Currently playing campaign with partner and I have also played some solo which works absolutely fine.
Same here, my wife loves the game! I do have plans to make a few homemade teams and scenarios of my won but i would love to see Free League release another box set.
