It did felt a bit like I was the only one growing up who liked Sega games... but I know there are a few British Sonic fans around.
I meant for modern SEGA franchises (Virtua series, Yakuza, Space Channel 5, Daytona USA, Chuchu Rocket, Super Monkey Ball, etc).
For old SEGA franchises (Streets of Rage, Alex Kidd, Altered Beast, Golden Axe, and of course Sonic) there are still a lot of UK fans since Mega Drive was the number one console afterall.
Sonic Adventure 2 was "unironically enjoyable". Especially given they couldn't re-animate the cutscenes for the english dialogue so the pacing just continued on without them. While it looked like Sonic was being a bad-ass cutting Shadow off like that mid-sentence, in truth it was bad pacing... But it still made such an iconic part of the game.
Bad or good, like it or not, Sonic Adventure was definitely a very memorable playing experience.
