I'll update the starting year every year, but the year selector is there just in case I end up late or forgetting LOL.
All of this game's big updates are honestly thanks to Toad22484's chat. They play this game every day and do 200 rolls on their stream and people suggest lots of silly things to add to the game, so sometimes I update and just add them LOL. Every new version is guaranteed to have something new, and it will likely be something random that you'll just come across while playing the game.
