I’ve said elsewhere, but for trading card games like Pokemon, Magic, etc, at the very least there is some longevity to the game if the parent company goes under. The rules of Magic are well documented and easy to find. If you have cards, the bankruptcy or buyout of Hasbro can’t stop you from playing with your friends at the kitchen table.

If Valve goes bankrupt, or gets bought out, or they shutter Counterstrike, what happens to all the skins you acquired in the game? Poof, they’re all gone. Nobody can play with the things they bought (or won in a game of chance) ever again.
