Sega to me is just Yakuza games + Atlus. (I wouldnt call myself a "fan" of sega)
Both of which are fantastic.
And occasionally something smaller, like Super Monkey Ball, Valkyria Chronicles ect.
I was never big on Sonic, and I feel like they didnt transition well into 3D era.
(ei. Im much more of a Mario guy, than a Sonic one)
