Mine is Pokemon HGSS (the amount of content is mindboggling), Pokemon Platinum (grandest Pokemon experience) and Pokemon Black 2/White 2 (most fun and unique playthrough). I’m also looking forward to buying Legends: Arceus on the Switch, have heard many great things about it!
I love the concept of Scarlet/Violet because I hate how linear all the other games are. The bugs and frame drops made me hesitant to buy one, but recently I found a physical copy for $43 on Amazon so I decided to buy it. Just waiting for it to be delivered now…
