What are some games you love but can honestly say you're only here for the core game and usually leave to make a sandwich when the actual story parts come into play?

I'm going to say Fighting games in general since most have terrible storytelling. Devil May Cry is also a series where the plot is touch and go, and even the few that had a decent plot, it's hardly worth the price of admission compared to that sweet sweet gameplay. Dragon Quest is also like this for me as well.
