1. Doom The Dark Ages
2. Expedition 33
Donkey Kong may be my number 2 as I play more of it. It's crazy fun and feels new and refreshing. Death Stranding 2 wows me every time I play it but I've been too busy to sink into it, and the times I've played left me feeling like I barely made progress. It may not even be a top 5 at this rate, over something not even really its fault. But I'm really liking NG Ragebound on my Steam Deck - that might climb higher.
Doom was perfect to me. Challenge, level length, fun, beautiful, smooth performance, absolutely solid gameplay that feels new yet is a continuation of a beloved franchise. I'm excited to 100% my save with the newest update and the expansion dlc whenever that's out.
Expedition 33 - much of the same applies except for it being a new IP. It doesn't top Doom for me because I feel the epilogue and endgame detract from the earlier core parts of the game. The end game specifically for me also feels, due to story reasons, kind of useless to actually partake in. But it absolutely nails everything else.
