I've voted for this, a bit late because I was on a bit of a break.
Splinterlands is like an anchor tenant for Hive (if you know anything about retail and shoping centers). The relationship is a bit complicated because Splinterlands is a huge part of the traffic of Hive (which is an expense) but it's also a major reason for the chain to be kept going. I came to Steem then Hive through @apshamilton and he brought me in via @splinterlands.
Everything I've done on @v4vapp and @podping stems from this. Indeed I believe there are only 4 unique functioning uses of blockchains which can't be done any other way: finance, gaming, uncensorable text/social and my own Podping notification system. The last of these, @podping, is 100% inspired by seeing all the custom_json data which Splinterlands puts on Hive.
But I understand Hive is competing with a bunch of VC megabuck funded chains who will all offer big $$$$ to move the game to their chain and take a % and pump some other chain up (and then dump it and cash out). And much of the $$$$ value they receive will be spent on stupid fees running another chain.
Hive doesn't have the VC megabucks but we have the DHF: we can help out.
But in return Splinterlands should do more to make it known that it is only the UNIQUE properties of Hive and the truly decentralised, community ownership structure of Hive which makes Hive special.
That's what I ask to see back from @splinterlands in return for my vote. @yabapmatt @aggroed.
