All the polls so far have been to decide the order of stuff, not if X or Y will be made (aside the 1st 2 batches). Polls are also a part of the rewards for dumping $ to DC, remove those and there's not much point of paying him (aside the hidden Discord channels you unlock by paying more). It's also the most direct way Patrons can "alter" the games's dev time. It's flawed and you get more votes with higher tiers, but that's the way things work for DC. Every1 and their mom will still get the game for free, even if the girl you moan about for years doesn't get anything until version 0.30 in 2040 (aka Debbie's preg remake and Judith)
