Create Advanced SEO Gaming Script

Looking for new gaming script to resell...must be good... UNIX PHP MYSQL FULL ADMIN/USER OPTIONS..HAS TO BE UNIQUE DESIGN..NEED TO ABLE TO UPLOAD GAMES, ETC... I HAVE LISTED A COUPLE SITES BELOW FOR YOU TO INVESTIGATE, OR INVESTIGATE YOUR OWN, BUT ADD AS MANY OPTIONS AS YOU CAN, NEEDS USER REGISTRATION, FULL ADMIN, AND DEMO MODE FOR SHORT GAME PLAY. [login to view URL] [login to view URL] I DO NOT KNOW MUCH ABOUT WHAT KIND OF GAMES GOES IN THIS TYPE OF SYSTEM, CAN YOU PROVIDE INFO ON WHERE TO GET GAMES, CAN YOU INCLUDE A HUGE LIST OF GAMES? I also mentioned SEO in the description, I want this gaming script to be very good and indexable by search engines, so if you can add some type of daily fresh content...maybe even googleize all the pages also so buyers can insert their google code easily from the admin panel. Any other ideas to improve on this? Suggestions? Your the coder, you let me know.
