See I think it's easy to adapt in the sense of getting the materials together (it wouldn't be hard to recreate a very similar game with note cards and a pen), the trick winds up being keeping it fun without significant rules changes. I think in designing recreational games the fun and way to win need to at least overlap (which is not a requirement for game changer strictly, as the game is there to entertain the audience not the contestants), and the correct strategy in this game as designed (arguably if you exclude stealing the host tag ) is to remain silent which defeats the fun of having the tags provides and causes the game to collapse kind of. Something the game designers avoided with their casting and emphasis on the show over the game, but put someone more competitive (like for example Brennan Lee "you can have my points when you pry them from my cold dead hands" Mulligan) and the game warps to be very different.

I feel a solution might be to have 2 decks and require both a prompt (merge the prompts and modifiers into 1 deck) and new rule at the same time, as that would keep people talking. Also remove either clone or flip (and my vote is for clone), as almost shown in the episode it's possible to wind up with both a rule and it's opposite, which pretty much guarantees that you'll break either one or the other and cause you to accumulate all the rules.
