YOu can be in whatever neighborhood you would like to be in... But if you are asking for an opinion, well the site appears to still be Under construction. If you are going to concentrate on gaming perhaps TimeSquare? Pick a neighborhood with a theme that you like and join!
can you add a rhythm game section? im going to make more content with rhythm games but also games
Unfortunately there won't be any new neighborhoods created in Neo-Neighborhoods, with the exception of maybe Picket Fence, Pipeline, and Augusta since they were actual GeoCities Neighborhoods... but they were added after the site makeover of 1998. To make any new Neighborhoods would require the creation of all new graphics from scratch and everything else involved... 38 neighborhoods is already a lot!
NeoCities Neighborhoods is for the most part a clone of https://web.archive.org/web/19970702235325if_/http://www15.geocities.com/homestead/homedir.html all the neighborhoods are the original neighborhoods of old GeoCities.
