Oh dude, let me tell you, the best DLC and most memorable DLC this past decade was the Booster Course Pass. Let me tell you, when I first saw that announcement 3 years ago, I was so pumped, I was jumping up and down, excited for more Mario Kart, I mean we started off with fucking Coconut Mall, I was already passing out of happiness, I thought we peaked there, but no no no no, literally months of free content, more tracks, ORIGINAL tracks, then we got NEW CHARACTERS.
Wave 6 was at my breaking point, because we got fucking DK Mountain, Daisy Circuit, SNES Bowser Castle 3 that was GOOD, FUCKING FUNKY KONG, AND HOLY SHIT . . . WII RAINBOW ROAD
I swear, if y'all known me back in 2023, I was addicted to Wii Rainbow Road, I love that shit like a son. The first time I played that track, I legit cried, like I realized now that this was the best Mario Kart because no other game is gonna make me cry of joy like Wii Rainbow Road, I was hugging everyone I know, Wii Rainbow Road made me love life
OH OH THOSE END CREDITS WHERE IT THANKED ME, MY GOSH THAT WAS THE CHERRY ON THE TOP
I molested my switch because that's how good Wii Rainbow Road and DLC altogether was
