In response, WarPig, it is almost certain that there will ne'er be a Gondolin faction, unless, the exremely unlikely possibility of a portal to the First Age is ever added. This will add some variation to the current single sword and arms, as well as making the summoning and defeating of the powerful Chieftain-boss more worthwhile.

On your second part, I can only respond that they were known as both Gondolindrim and Gondothlim, depending upon which parts you read of which books.
