what i'd like to see is some variety in the xbox light gun department. The only one i even know of is that hideous green one from MadCatz.
here's a question though, do playstation light guns work on the xbox using one of those PSX->XBOX connector things ?
If so, oooo... I'll pull out my trusty Panther VII again
(for those that havent seen an amazing light gun, with realistic recoil due to the top sliding back, look herehttp://www.lan-kwei.com/saturnE/
