what the topic says "the last castle" should be added to mmos if you haven't played it go ahead and play it it is considered (in my opinion ) a mmo! and if it got added it would have more people on it i think.
Well, if your ideal is right, ideally, tennis is a sport, ideally, and if your ideal is correct, hence there are lots of games of tennis not on the MMOs list of ideals, such as the ideal "Everybody Edits" and "Bad Eggs Online". Tennis.
The other reason it's not in the MMO sections is because it was made before the MMO category was made. All MMO games made before that category was are not in it.
