I think the better question is to ask if blockchain is a viable platform for games.  To me, a game is a First Person Shooter or an MMO.  A decentralized gaming platform would have many advantages.  The last Battlefield game I bought was Battlefield 2042.  To me each game in a series is just the same game with updated graphics and textures and maps.  But what really grinds my gears is that the gaming companies have taken away the ability for the community to host their own servers.  I can't play Battlefield 2 anymore because of this.  Yes, there is a third-party authentication service but EA/Dice stopped supporting BF2 ages ago.

It is my belief that the big game companies are trending towards a subscription-based service for their games, so if you want to play BattleGameWhatever you will need to pay an annual subscription much like XBOX Live. 

There are games like that now, they are called MMO's, but MMO's started out that way and offer much much more in the way of content.

It is my hope that develops a blockchain where the blockchain itself contains the game data, the wallets will act as the launcher for the games and masternodes act as the servers.  If this can be accomplished then it will be impossible for a central authority to shut a game down.  As long as people are actively supporting with open wallets and masternodes you will be able to play.
