Looks like Shockwave is the preferred method for creating Web-based games. I’ve been at various sessions and roundtables here at the Game Developers Conference and many technologies are always mentioned: Shockwave, Flash, Java, Wild Tangent and ActiveX. But Shockwave seems to be the one universally accepted and used by most. Flash has been mentioned several times as something that is too slow for anything but simple puzzle games. The others just aren’t used nearly as often.
