Isn’t Baldur’s Gate 3 just DnD, so thats easy as I already have that knowledge. All the others don’t seem that complex.
Deep Rock is Shoot Stuff, mine, don’t die
Overwatch is only complex when you get past the early learning and pissing around and start learning characters and trying to counter pick. Which you don’t need to do to have fun.
Destiny I don’t remember much of. I guess it had some more complex movement and stats so that one might be more complex.
