I do hope that the full release doesn't hide too much, if any, H-Content behind SS tokens. S Tokens aren't too annoyingly demanding to get, so if anything I'd go with putting that kind of stuff there. Maybe put in optional modification unlocks for the minigames, reward those who play well with ways to make things less or, even better, more of a challenge. Maybe something like making certain buffs/debuffs spawn more or less frequently when using them, for example.
