There are much better methods than subscription plans but people have a long way to go to advance to that level of societal ingenuity(Greeds a bitch). I wanna puke and eradicated technology every time I see a subscription plan. This game in particular at most I'd say 20-30 bucks worth especially if it's truly worked on. If it took inspiration from other similar themed games it could be made into a bigger game with several times the content and freedom of options. This is a pretty damn good game for the type of game it is, as always proper improvement will only make it so much better.
