Worth it for solo casual player?

So I'm looking for some action games that have addicting gameplay loop because of simply fun. Also I don't have friends to play with so I mostly play solo so I don't wanna buy a game that depends on having a group to play if you wanna have fun.

The other thing I'm looking for is a game that's easy to pick up and have fun in a way that you get to the fun stuff right away without too much wandering around. Let me give you a counter example of this: I was playing Dragon's Dogma 2 after a long day, although the game is great, constantly opening the map, trying to see where im going, and wandering around for a long time before getting into the meat was really tiring for me.

And a good example of this is Armored Core 6, where you start up a mission and get to the action. I'm saying this because although DRG looks great to me, my concern is, as it is a mining game, is it more about the mining and cave exploration more than the shooting and fun? and are the mining portions of the game fun mechanics?
