Even giving top people the option to vote on which of two options you *might* take the story is too much. You need to add both as options for players to pick as they play.
As others have noted, some good games have been side tracked, or 'surprise' fetishes added to what seemed a game not focused on them due to high tier Patreons. I swear some of them are trolls just out to derail games when dev's are too weak to push back. Hell, even giving the top people the ability to have one path focused on over others could end up with a series of updates that cater to one path, which can and will kill a game, even if long term the plan is to flesh out everything.
People will abandon and ignore games when one fetish in a laundry list, or multiple path game, has more renders, story and scenes than other paths for more than one update or at most two. Sure you will get some that cling on in the vain hope things will correct over time, but 99% of games that start to focus on one path, when there are two or more, never recover before a good portion of their potential audience vanishes.
In any event, as a dev it's best to consider who your core audience is, and if you're walking a tightrope like with multiple similar but vastly different fetishes that could literally turn off a good portion of your audience if there seems to be favoritism, make sure you are equal and impartial in how the development goes. Never have one fetish start to blend into another one, because that causes all sorts of chaos.
EDIT: By the way, if the game is really going to focus mainly on one fetish even there are multiple options, please do all of us forum goer's a favor and actually list that in the dev notes, have most of the sample pics showing that, etc. There's few things worse than the OP implying there is choice in any game when there really isn't, and there never was a plan to. Sure, some games that's the 'hook', that illusion of choice, and most will learn to 'read between the lines' but it tends to make any game that has a 'hinted premise' more wary of even bothering to check it out, as a side effect.
This is ESPECIALLY true of any couples games, where 99% of them end up the woman in the pair becomes a total cocksleeve for everyone but the guy she supposedly 'loves deeply' even IF the description implies there will be actual options/choices along the way. Most 'swinging' games becomes mostly 'sharing' or NTR where the woman get's like 95% of the action with everyone but the supposed partner in the couple.
