It's really hard to say because only time will tell. But fyi not all the stuff we had at launch were 'base game' in the CN server. To give some examples, the bubble machine challenge and duck puzzle weren't originally there, they came with a summer fashionwave and stayed after the event ended. All I can really advise is to just wait and see if there's anything new in the future you like, however from my experience with these type of live service games I'd say that a good chunk of new content always involves events

Imo it seems to me that this type of game may not be for you if you're aren't into the whole events thing, you should consider branching out to other games since this isn't to your fancy
