Now as for why this thread continues when the main series is depleted of talking points? There is a plethora of both official and unofficial spin off games that fans of the main series may want to try. These games are generally less popular than the main games so they have not yet been over discussed the way the main series has. In the case of the fighting games like 12.3 there will be a lot more to discuss as the other players are equally important to your experience as the game itself which of course opens a whole new avenue of discussion.
So yeah just chill, people in here appreciate the main games its just that there is nothing new to talk about on that front.
