^ Are you paying for the game ? Nope, you pay to help DC make what he wants, this isn't Kickstarter
Is your pledge paying for the game ? Nope, you pay for the tier perks
Is the game behind a paywall ? Nope, every1 gets it for free
Would the game still be made if your pledge was not there ? Yes, unless you can convince the ~25k dudes to unpledge overnight, the game will still come out
So, how is any of this milking ? You don't pay for the game, you pay for tier perks to vote in polls and get roles on Discord, you still get the game for free and your pledge doesn't mean anything in the ocean of dudes pledging.
