LRG has put out so much nonsense (honestly seems like they just look at potential cover art as their decision maker for pursuing a title) that it's become clear what will be worth something from LRG and won't. Popular, good titles (Shantae) are worth the most. Popular, mediocre titles (Night Trap) are a step down and then there's really everything else. If you want to play the LRG game, you want a case of NHM and Curse of the Moon 2, not so much Hero Must Die Again. Scott Pilgrim is going to be worth more in the long run than the bulk of the LRG library, regardless of the metric ton of copies, because it is good and fun.
And of course, whether any game stays "valuable" remains speculative because any LRG title can be reprinted by another publisher. Sure, it may not be the LRG "version," but I wonder whether that would matter with games. It's not as if it's a movie where one bluray release to another may differ in visual quality and special features. This would be the exact same game just published at two different times with some different outside art.
Anyways, the whole collecting for the sake of collecting is an approach I don't understand. I buy movies and games, but collecting is just a collateral consequence. I buy games to unseal and play, and movies that I want to see and enjoy. The fact that some of these items may become "valuable" doesn't really factor into the equation.
What annoys me most nowadays is that due to SO many speculators, flippers, and others who just buy stuff (i.e. have zero interest in the game, movie, etc.) to "make money," I wind up finding items that should be in sound supply just disappear from storefronts and wind up in droves on eBay and Amazon. I'm not saying folks don't have the right to do this, but it's just annoying for those who simply want a game, movie, or whatever else it may be, to just consume and enjoy it.
I can't think of another industry where FOMO is as frequently and actively weaponized against consumers - whether by the game-makers themselves or speculators - as it is in this one.
One could say it's gotten out of hand, but I'm not sure there is any way to stop it. And frankly, I'd be more concerned if any regulatory body tried to do so with something like this. It's a first-world problem.
