Variants in general are sold in that manner, and are limited in that it is a "variant" when it was produced, sold and advertised.
I'm not going to say the ESRB won't be a selling point to someone, but I personally don't see that adding anything to an already "limited" item. Will B&C now be worth more simply because it isn't rated, when newer games will be?
Honestly, I see both sides of the equation being discussed here, but it's a "chicken & egg" argument. I don't know that anyone could ever prove the ESRB has driven up the collector's market, unless at some point games that didn't command much start to over time, but who's to say that didn't come from more consumers wanting it, and less qty being available?
I can't see the lack of ESRB changing anything. The rarity of a game coupled with the lack of copies on the open market tied to people being willing to pay a higher price for them plus sellers being brave enough to keep prices high until the games sell... that's what will determine the market for these things.
The only effect i can see the games with the ESRB having is that they will appear more legit and that may attract a few people in that opted out of the LRG games because they weren't fully retail ready games. Retail games have ESRB ratings and a registered barcodes.
Before anyone says "all the games have barcodes", they are all also forged from some Utah company called "On The Rocks, Inc." and LRG also overlapped barcodes between a few games (look at Drive Drive Drive and the Shantae games). Unlike say Root Letter which it's barcode is legit registered to Pqube Ltd. and Soul Sacrifice is registered to Sony Computer Entertainment of America. LRG doesn't appear to have ANY legit registered barcodes on their game releases unless they are secretly owned by On the Rocks, inc. or have partnered with them.
You can look barcodes up here to get the company info: https://www.gs1us.or...-database-gepir
You can use the R1 Directory Tweeg put together for barcode info: http://www.tweeg.pso...1_Directory.pdf
Just keep in mind you can't easily copy from the R1 directory... but typing the codes in isn't a that hard once you look something up.
Also none of this stops the games from being legit since sony manufactured them and approved the games. But they just haven't been legit retail ready releases until this first batch goes out... and even then they will probably still use forged barcodes on the back. None of that though will change them from being super low printed games that have value mostly based on purposefully limited availability.
