A Passing Parcel Game

Played Unlocked yesterday, one of the physical board game takes on the escape room genre. It was fun solving puzzles as a group, but I'm not sure I'll dare do a real one, even though I have some friends who have asked me.

Anyway, back on subject: there's no replayability to the game. Once you solve the puzzles, there's no way to change the clues. It's similar to a legacy game in the regard. As soon as you open envelopes, stick on stickers and modify the board, there's not much else you can do with it.

Could you make a game in which you are presented with a puzzle to solve, but once it is done, you'd change something about it that will give a different experience to the next group that solves is, maybe even so far that a few playthroughs by other people will change the game enough that you could play it again yourself, without already knowing how to solve everything and how it ends?

Co-op Minis - Kaijus

A kaiju theme for the co-op minis game I came up with.

Take command over policemen, soliders or super sentai heros to defeat mini-bosses until the conditions are right for the main boss to arrive

Maybe everyone controls a different team of plucky teens that turn into themed super heroes (i.e. Masked B-Boys, Construction vehicle robots or natural elements, including weird ones like mud or clay) and have squad cars or attack helicopters as support units

Harass monsters to enrage them for different abilities and to guide them to preferred locations. Complete different goals such as rescuing citizens and saving as many buildings as possible, while ultimately still needed to defend the boss.
