There is a different incentive. For an offline single player or LAN game, you want to make the game interesting to play enough that the player will buy the game. For an online game or a microtx based semi single player game, you want the player not to play, but to pay, over and over. That means that engineering addiction that leads to nothing but payment and compulsion is very profitable. Offline games can definitely be very addicting and engaging. But ime those that are are because you're trying very hard to do something difficult, or because you're exploring, or because you're creating, all of which are ways in which video games can plausibly be helpful. And you will eventually get bored or move on to another game, which will give you time and pause to reconsider what you're doing. Meanwhile you could be grinding an online video game doing menial tasks and buying microtransactions without ever having an end goal in mind and without being creative, for over a decade, every day. So I think they're very different.
