I like to keep the CSS in "Classic BlueSteel". The "uniting hunters of Ragol" slogan is just too catchy for me. (though the more modern BlueSteel is well-done; that's why I hope new ones come!)
SONIC TEAM should release more promotional images like the ones they did for PSO, with random hunters (like the one below) ...
It helps build up the character of the game, and that whole "you're not the only hero" vibe. Plus, the art style is really cool.
A lot of PSO players turned out to be very talented artists, creating amazing masterpieces of their characters duking it out on Ragol. That's one of the many things that made PSO so fun to play! I hope we get to see much more of this vibe with PSO2!
