Anyway here are some of the reasons why people joined Sega:
Game Planner:
Golden Axe was the funnest thÃng on the world for him, and he thought with House of the Dead, Segagaga, Sangokushi Taisen that Sega was a very "edgy" company.
Designer:
Liked Puyo Puyo and Yakuza, and the wide range of businesses Sega is involved in (console games, arcade games, amusement centers)
Programmer:
Was impressed by Yakuza and Valkyria Chronicles, so would join
And a foreign applied because of Sonic the Hedgehog of course!
