I'm going to dissent, and believe that you can't have simplicity with codified depth and tactics. The more you add, the more complicated you make the game by default. It's a sliding scale, with 5E closer to simple (especially basic) and PF2 closer to tactical. You could have a game that runs between them (or one may exist), but it would be hard pressed to market against those titans. I think that PF2 has taken a good direction, moving away from 5E simplicity, because that allows them to fill that niche for players who want that.
