By that logic, Shenmue is also a Christmas game. You can even talk to Santa Claus in the game; he tells you to go a Chinese restaurant or a bar.
About Blue Stinger: I could never get into it. By the time I played it, I'd already played Shenmue and other really good DC games, and Blue Stinger seemed pretty weak in comparison to those games. I think the main problems I had were the controls, which seemed very clunky, and the graphics - which were nowhere near as good as some of the better games for the system. Still, I've been thinking I should give it another try - I might appreciate it more now than I did previously.
