Sounds like a great idea to me. :D The question's always - which game warrants a section entirely dedicated to it?
Maybe instead of starting several sub-sections for specific games divide the Other Games section into "Other Games - Historicals" (for the Bolt Actioneers, Chain of Commanders, Hail Caesars, Flames of Warsers, Black Powderers, Sharp Practitioners and so on), "Other Games - Sci-Fi/Fantasy" (for Infinitineers, Dystopians of sea and land, Malifauxeurs and so on) and maybe install a seperate Fantasy Flight Games section for X-wing, all their roleplaying games, team manager, death angel, talisman, that upcoming x-com game, the Star Wars Space Crusade that's soon to be released and so on.
IF a certain period of historical gaming (according to the Great Wargaming Survey that'd be WW2 of course) should prove to be overwhelmingly stuffing up the Historicals section you could consider splitting historicals into WW2 and Other Periods. Same goes for the Other Games - Sci-Fi/Fantasy section. Infinity has always been there and rather popular with some but on GW-centric forums it never seems to really break through a certain threshold number of people who like to chat about it on forums. However, since the new edition's about to be out and such maybe there'll be lots more people to play and maybe that might be a candidate for a seperate section itself.
Very good points raised there, and they have been jotted down
