Please don't feed the trolls

Given building the Harem is 'the game' and there is no end game content being able to channel energy into any kind of farming would be nice too.

And the idea of perma locked content doesn't sit well with me either, yes the dev can open the vault whenever they like but a more structured way would be appreciated - I'd rather not have everything koban locked - and hopefully part of the rethink will vist the cost/koban ratio

Perhaps after a time, or once a world is farmed out the bosses could drop tokens, and these tokens in time could be traded for old event girls....so say you wanted event girl X, boss Y drops the tokens, you need to farm all 3 girls then say 3 tokens....as rare as a girl drop...to get 1 girl

LOT of work, but end game....
