Their pricing scheme was explained also bazillion times.
Prices on Steam matched kickstarter fee for access to that stage.
As for the game.. I'm disappointed - no campaign or something like that. I think it was in kickstarter but might be wrong on that point didn't check again.
I have it now and it's not my kind of fun I think (after leisure playing for about 1h I sent some sats to scout.. AI had hundreds of units.. all around the place... it didn't come to wipe me out in all that time but I had no chances with it )
Feh, explanation or not, I still deem it stupid. LOTS of other developers are capable of coming up with better pricing models... there's no reason these guys couldnt have found a better way. As it is, WAY before the game has come out, they've already caused a good chunk of players to decide to never buy the game, because of that. It's one of the most frequent things I hear in relation to the game. AKA, *not* a good business move. It is, though, a superb way to get on the road towards having a reputation of being really greedy. Both are things that only lessen the potential sales that they'll get. Fortunately for them, the game itself looks to be shaping up to be something great.... so a move like that isnt likely to damage them too much. In theory.
Me, I'll still get it, but then I just tend to buy whatever the hell I want regardless of anything else. Unless it's something by Nintendo, I'll always resist THEM.
As for the difficulty you mentioned, the developers have said that difficulty settings/sliders are coming (may already be there in most recent patch?) as that's a comment they've gotten from alot of players, is the AI being much too hard, particularly when learning the game.
They also had some.... very unique ideas about the "campaign", which apparently wont be anything like a normal campaign. I'm not really sure how to explain it without getting the explanation totally wrong.... best to look up what they've recently said on it. I heard it on their Twitch stream a day or two ago.
