It is different, because one funds a kickstarter with the expectation of a somewhat complete product, ESPECIALLY when said developer SPECIFICALLY limited the higher tiers in terms of what they thought they could reasonabley manage and still failed to meet those "contained" expectations.
‘the expectation of a somewhat complete product’ - you’re describing what they’re already doing, releasing the game in large portions at a time. Unless you’d have rather they drip feed you one or two missions, a planet to check, and one scene of dialogue a week.
Also what part of the higher tiers have they failed to meet? The community isn’t exactly starving for things to do, so demand for Studio 69 (which doesn’t add anything lewd remember) isn’t really high at all. Backer planets are in, whale scenes (the highest tier) are in. Everyone that backed got a key (with a ticketing system for those having issues). They unfortunately can’t do anything about countries’s laws, but they’re working on an alternative on the side.
All the while keeping the public updated to their progress on a monthly basis.
Now tell me about say Icstor, Milfy City, and how long that game went on for without an update before it eventually got abandoned.
