But I don't care about the sun being a 2D sprite or a model. I prefer that Schema add more useful things before. And I'm sure you too.
Anyone coming in a Early Access game expecting a fully polished and finished game is a little bit idiot or misinformed. It's a chance SM is enjoyable in Alpha.
By definition, polishing and graphic improvements are in beta stage, same for an API (modding is useless if you have to change everything at each update).
So there's no point arguing. One can simply enjoy both games. And sometimes prefer the original one, think about Ace of Spades, actually there's more people playing the old free 0.75 version (even if there's tons of cheaters) than the fagex 1.0 version.
