For me it’s first person puzzle games. I can think of maybe a dozen off the top of my head that came out in the last decade. I especially enjoy when they’re open world. The ability to just quit a puzzle that’s stumped you and go try something else for a little bit is incredibly refreshing.
Generals with Zero Hour is fantastic, and I actually think it’s the best in the series. While I think Company of Heroes is better, it’s still a very good game.
