People are getting crazy ideas just by seeing some words.
"Cabinet" doesn't have to mean anything else than "the group of leaders who provide bonuses".
"Tax" doesn't have to mean a proper gameplay feature. It could just be the revenues you get every turn.
And so on.
It's very likely a mobile game, folks. It won't have deeper gameplay than PC or Console Stellaris. It will just have shiny, purely consmetic names. The only gameplay we've seen are some events that influence your ethics. We can also see that there will be money, ships, research, trade caravans, colonization and pops. But all this will likely be at a very basic level.
It doesn't mean that the game will not be unenjoyable, but ti's still way too similar to "regular" Stellaris for my taste. It looks like a strategy game for mobile, and no matter how I think about it, it's a bad idea. There's a reason why the genre isn't very popular on mobile. Well multiple reasons in fact.
And anyway I just don't see why I would play a mobile version of the game, even if it has some differences, if overall it's just a lesser adaptation of the game. I hope there's some interaction between the app and the game on PC because that's probably the thing that would make sense here. Otherwise I just don't see why they would tease people who already own the game with that announcement.
