Some people seems to misunderstand the concept of patreon, you are not paying to own the game, you are donating to help with the funding because you want the game to be realized.
If you're doing it for any other reason you probably shouldn't donate, especially not if you feel like they owe you something beyond the tier rewards for donating.
While this is technically correct, in practice almost nobody would pay any money for such a model which is why patreon offers rewards, in this case a new build every 2 months + a smaller update a week after a big update. That being said, I don't think aiming for AAA quality AND AAA scope is a smart choice when you don't get the resources of an AAA studio.
A better idea would be to create a smaller game with stunning visuals, which is what the team around Adeptus Steve is more than capable of. Throw in a bit of gameplay with a lot or replayability and you're pretty much set - a lot of indie studios compete with AAA by coming up with clever ideas to squeeze as many hours as possible out of their game instead of padding it with endless filler content.
For Wild Life specifically I'd have developed a small arena fighter. That way, you can get by without wasting time developing complex maps, a few arenas + maybe a hub area or two would've been sufficient. Have a character editor and unlock sex scenes by defeating an opponent. Now you can tweak the combat system to your hearts content and you also don't need to worry about spreading your time and money on all areas at once. Throw in a few new animations each update and you technically not-customers are happy.
Now you have an update cycle of one update every two months with not much changing from the player's perspective, the only thing to look forward to a new toys in sandbox if you're into that and new animations, of course. But you might not get the animations you're looking for - for me, the most interesting animations involve male anthro x female human, especially anything involving the Kral and Maya rigs. There's sometimes multiple updates in a row without any meaningful content in that regard - If Kral would get the same love as that stupid little goat fucker I'd actually consider supporting because I don't really care that much about gameplay.
