A coop PvE game for two dads and three sons?
A shooter, preferably. Any recommendations, #mastodon guys? The youngest lad is 10, so as little violence as possible. Thanks 😉
I know you asked for as little violence as possible, but have you considered Destiny 2?
There are single, two, three and six person activities (and you can use group finders to help find a 6th and maybe make a friend on the way).
It is a first person looter shooter, but it also has a deep story as well as mechanics (eg platforming, solving puzzles, exploring areas to find collectibles). Ultimately though you do need to shoot and kill stuff. It’s not that gory however.
There’s also builds in the game, so you can spend a lot of time tweaking your builds to get it how you like it, aka theory crafting.
It’s also “free to play”, but in reality it’s “free for the first bit and then if you want access to heaps of other content you gotta spend money”.
