Pokémon Legends: Arceus for me. The beginning didn't catch me and the new mechanics and button layout confused me a lot. Then there is the fact that I couldn't hear much music, which is something I usually enjoy a lot, but all I heard was the town theme and the battle theme, that's it. I put the game away for like half a year but then decided to keep pushing through anyway because momma didn't raise no quitter.
And I liked it in the end. After a while it got me hooked. I think it is kind of refreshing for the entire series and it even has quite a lot of good and catchy music in it. You have to actively look for it, though, don't get interrupted by annoying random battles and even then it is tuned down a lot, but still. The music sounds way better when listening to it in Youtube. So all in all, it is a good game and I enjoyed my time with it.
