For me it's Eric Tomizawa from Like A Dragon, Liam and Milo from Monsters Prom, Lifeweaver from Overwatch, Boone from Fallout New Vegas, and Astarion from Baldur's Gate 3.
I LOVE yoshitaka mine from Yakuza 3, one of my fav villains from the whole series. I totally get the love for tomi, hes so bbg. Hows infinite wealth for you so far? im on chapter 12 rn and im busy grinding out the characters.
I think I'm only chapter 5 or 6 because I haven't felt like playing due to depression. Thinking of picking it back up again. I'm at the island right now but I've already spent almost 40 hours in the game already due to just running around Hawaii. I'm already almost done Eric's bingo card
I haven't played the older games but I've been thinking about doing so if I run out of things to do. I just normally don't play beat em up games. I love the series so much though. I even bought the rare Yakuza Dead Souls NA release off my dad to kick start my collection. I fell in love with the first Like A Dragon.
I didn't really get into sonic but I could see myself EASILY falling into the fandom. I played the GBA games a lot growing up and Sonic Boom was my type of humour :D
5 years is a long while. I think my longest character obsession would be Genji from Overwatch but overall hyper fixation I've been obsessed with Spongebob for about 16 years
