The Universal Century line was the main production line so there were a lot of models in there already. Then there were the new anime series that came out and that rapidly added to that subsection. To trim it down I decided to put up 3 new sections: Wing Gundam Color Guides & Manuals, Gundam Age and Gundam Build Fighters.
If you are wondering why I decided to split the Gundam Color Guide & Manual subsections according to anime series. Its because its easier for a fan like me to search through the database that way since I'm familiar with the different models (usually...hehehe) after having watched the shows. If you are having a hard time with this system, I suggest using Google to aid you with your search. Use the "site" function of Google to specifically limit it to this site.
For example, if you wanted to search for the MG Build Strike Gundam, then you would type this in the google search bar:
MG Build Strike Gundam site:mech9.com
Hope this little site modification helps all of us. Good Luck and Happy Building.
