Platformers are definitely the games I enjoy the most, especially if there's some degree of freedom in how you complete levels or progress through the story. Though I hadn't played it for years, replaying the Spyro trilogy made me realise just how much of the content in those appeals to the stuff I like in games; collecting, non-linearity, not taking itself too seriously, and so on. I like Ratchet and Clank for similar reasons, which makes sense because it's Insomniac's successor to Spyro. The Dreamcast Era Sonic games, Crash and unsurprisingly Mario are also some of the platformers I enjoy the most. It's a genre that seems to be coming back as well, which has me very excited for the future. :D
