Nice analysis and interesting to note how generous you were with the user base... i saw how they talked to you when you even mentioned Splinterlands... it was like a Mob.
But yes I'd agree with many of the points... It's true their game play is more refined on GU for sure.
However Game Play can evolve and get better and I know it's happening (slow as it may seem to happen)
BUT the foundations won't change and seeing all the features we've been able to do on Steem with the Peakmonsters.com market is amazing and how quick and easy it is to do... those developers would be crying with joy if they were doing the same markets here on Steem.
This is not a Knock on the game as it is very good nor a knock on their players for liking the game and they didn't have any choice in blockchain. But they're putting up with inconveniences that they're trying to tell themselves aren't so bad.
Honestly they should just do a market for GU on Steem. Heck we'd host a good programmer to do it on PeakMonsters and help them out. Save crazy amount on transaction fees etc. Card transfers would still be ethereum so that's gonna be slow but looks like there is still a need for a bid market or a USD market.
