How so? I imagine most people (including myself) aren't familiar with the mobile ports, so I don't really know what's supposed to be remarkable about those.
Simply put, they did a great job of them. They run well, and they added little bits of polish that would mean, assuming touch controls could be as good as a mouse and kb (and tbh they're really not bad at all on a tablet/ipad), it would be a superior version of the game when compared with the original PC release.
I guess that experience and them going above and beyond / and also having very personal engagement when it comes to customers, well... it's a far cry better than what you get from most game studios?
It took weeks of pestering on the discord to get them to admit they were actually working on a patch. They've also been extremely vague about their plans with the modding limits.
I dunno, different companies have different standards of openness when it comes to their internal processes. There's a real problem in games where once you announce something people quickly get impatient / have little appreciation of the amount of work required to pull off popular demands. I'm far from competent with game engines or anything, but I'm aware enough to know that people complain about things with very little notion of what's actually required behind the scenes. There's a common misconception among a certain segment of gamers that if something is a small change in-game, then it must also require only a small amount of work to bring about. And it just isn't like that.
