I think the problem with bigger gaming companies and Web3 is that Web3 requires a loss of control for those gaming companies. Using Fortnite as an example, a Free-To-Play game has made astounding money selling purely cosmetic items.

Epic Games doesn't really want gamers to sell those cosmetic items to each other, because then they aren't buying them directly off Epic Games. Players could potentially sell their whole account to someone else, but they can't sell individual items.

The loss of control is a big deal for bigger companies, using a public blockchain potentially means they can't offer the same support they normally do, and it opens them up to all sorts of smart contract mischief (see Adidas as an example).

Personally I see Web3 as perfect for smaller companies with a fanatic fanbase who would be happy to invest and grow as a community. Splinterlands so far seems to have been fairly unique but I'm excited by the other games being developed on Hive.
