It is indeed. all the "variants" they list for each game also include the detailed description. Anything mentioning "cart", for example, is a reference to only something you'd know with a CIB game.
It's confusing though because they mix ALL variants together: countries, CIB, sealed, even some vague variants that make no mention seal, tear strips, or carts. It's pretty vague all things considered.
I'm currently seeing how easy it is to parse out CIB vs sealed for strictly USA games and tbh, i'm considering just grabbing the data and dumping it for someone else to parse out. I'm not super educated on all the variants for a given game.
