I saw a rock on the ground, picked it up, and yelled “YahHaHa”

I won’t necessarily dispute that.

If Blockchain tech really did solve a gaming problem in a unique way, it would be done under the hood, in such a way that developers and modders could use it to add value, but casual gamers wouldn’t even realize it was being used. However, it’s harder to get funding based on buzzwords that way.

This was in fact the original purpose of cryptocurrency. The seminal Bitcoin white paper is titled “Bitcoin: A peer-to-peer electronic cash system”.

One reason to include blockchain tech in games is to enable trading of in-game assets without needing to build a trading engine from scratch. It also offers the chance to tie in-game assets directly to real-world values, and have certain assets be useful across games in a franchise. Basically everything Magic The Gathering or Pokémon does, except that you don’t have to worry about the cards deteriorating as you use them.

Once you realize that Magic and Pokémon were just cardstock NFTs all along, the whole idea of NFTs in gaming start to make more sense. Not every application that the the Crypto Bros propose to solve with NFTs are really appropriate, but some are.
