They share nice little projects, even Planet Zoo
Planet Zoo has been a top5 Steam seller for the last five weeks, gathering a 87% from almost 15k reviews. JWE was top5 seller for two months IIRC, including hitting #1 for two weeks. These games are honestly quite massive, it is just that they appeal to the more 'casual' gamer so you dont hear as much about it in gaming communities. I wouldnt be surprised if JWE+PZ earned FD more in actual income than CIG got in 'pledges'.
