I’d highly recommend Stolen Realms. Pretty cheap too
It’s a hex grid turn based game. You can have up to 6 characters (difficulty scales per character) and can each control as many in the party as you want. Turns are taken as enemy, and players with the players able to act at the same time so you aren’t waiting too long if you are communicating about what you want to do.
It has multiple “classes” with skill tiers that require you to take a few from that “class” but you can spec however you want.
The roguelike mode is very fun for quick sessions and will reward you with a choice of random skills and armors after every fight, but it also saves if you need to go and play later.
