Boo is my favorite, so my 2nd and 3rd would probably be... Waluigi and Luigi.
Honestly, that's also my pecking order for who I main in the Mario Kart games, too. If no Boo, then Waluigi. If no Waluigi, then just Luigi.
There's no harm in looking things up occasionally.
There's no one keeping score and nobody else really cares about how you play, so you should just play for yourself. If someone does grill you about how you achieved things, they're not superior in any way, they're just being a jerk.
Honestly its just Mario & Sonic racing games for me.
I liked playing some realistic racers like Cruis'n USA for N64 and Midnight Club for PS3 mainly due to the mindblowing graphics of those games (at the time). I don't actually care for real cars.
The Dragon Kart minigame in the Yakuza series...
I juggle multiple series until one becomes an obsession that I'll focus on until I see it all the way through... then I go back to juggling again until I find the next big thing for me.
I just bought this game a few days ago. I grew interested in this game after seeing a trailer for the Evangelion and Godzilla DLC packs. I wasn't expecting there to be anime & tokusatsu crossovers, that's so hype!
My main in the game is Dojima from the Yakuza series.
