Please make it.
Rather than running a 10-person raid on a dungeon filled with Ice Spiders, what if were 10 customers in a bank that was getting robbed? Or if you’re one of 10 firefighters trying to put out a fire?
A safety escort of a dignitary.
An group of officers in a car chase.
Add in 5-person versions as well, 5 customers in a convenience-store robbery, instead of the bank.
I’d play an MMO that consisted of game or puzzle interpretations of real-life scenarios.
