Quoted from Frax:
it feels like it's REALLY REALLY early for a game based on it to be coming out.
I think you focus on the main themes with a few small payoffs for the shows big fans. I was thinking about what you absolutely have to have: Rick, Morty, alcohol, portal gun, and the space cruiser. I'd also toss out Mr. Meeseeks, which seems like a great collection feature like the diamonds in Congo or ghosts in Ghostbusters. Maybe an add-a-ball multiball. I honestly think everything else is optional, but they should at least reference: Jerry, Sniffles / Snowball, Get Schwifty, Council of the Ricks, Pickle Rick, Evil Morty, Mr. Poopybutthole, Birdperson, and Scary Terry.
