Great post! I'm very excited to see where we end up with block chain gaming in the near future.
Talking about the old days got me feeling really nostalgic, I used to run Counter Strike servers back on patches 1.5 and 1.6, that's even before Steam existed, let alone all the CS games that came out since!
It's unlikely that any AAA developers will embrace blockchain tech in a way that will limit their control over their IPs. Blizzard famously refused to give offline play to SC2 because they wanted to maintain a tight grip over the burgeoning e-sports scene; the global trend is increasing centrality, largely for financial reasons. Indie devs on the other hand will give us something unique, but that also means suffering the deluge of low budget pixelated side-scrollers until the tech has been worked out.
