Well if it is, I sure am glad I sold most of my stuff off to get a beach condominium.
But I would say YES for the following reason - I think remakes will be the killer. What kept this hobby growing was the quest for that sweet original limited MM, AFM, CC, .... Then someone comes along and builds a modern version of the game that has huge differences in platform and most don't care anymore which is original and which is a remake. Too few think it matters. To me it does but I sit in the small minority, maybe because I took on the quest 15 years ago to get my MM.
But the new guys in the hobby could care less. So if all the popular titles like MM, CC, MB, AFM, ... get remade, then it will all crash. Remakes will fetch 5/8 of what they sold for new and originals will probably get an extra 1/8 from nib remake prices, and that will only be if they are in nice shape. If not, they will sell for the same price as a used remake or slightly less.
This doesn't even include the flood the market is about to experience.
I am glad I got out.
