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.
Tower Defense Games
Linear First Person Puzzle Games
We’re living in a golden age of tower defense games. Sanctum 2, elements td, dungeon of the endless/endless dungeon, rogue tower, dungeon defenders awakened, orcs must die 3, bug tdx, tiledeck td … Seriously there are so many. Even Path of Exile has a tower defense mode.
