Hi Myriad Force,

I presented Jez (the developer) with your question and wanted to relay his response:

Ethereum is the network of choice right now. Not sure lisk would offer us much benefit. Ethereum is a rapidly innovating and well supported network.  The ecosystem is very rich and there's a lot of assets on the blockchain which gives us access to customers who have funds.  And since all tokens are erc-20 compatible, automated exchanging from one token to another is quite trivial and lots of exchanges will support this, as will protocols like 0x etc.  

In short, we get a lot of benefit in being on the ethereum blockchain and although its technically feasible to run on other smart contract enabled blockchains, it still might not be worth doing if the rest of the ecosystem isn't there.

Another quote from him that further elaborates on the benefits of utilizing Eth:

"Sciguy, other reasons.  Winter is coming!  Sorry, i meant, Metropolis.   it brings new features that we really like as well.   like EC math (lets us and other people do zk-Snarks, for good privacy, but more importantly for us, lets us do BLS random numbers (aka herd randomness, ok, I just made that phrase up).  Also, in Metropolis, the contract is able to pay the gas, which further lowers the barrier to entry of new customers playing with FUN for the first time.  ie, their account only needs FUN in it, and doesn't need any Ether as well."

To add to it, in this interview, Jez explains how the only time a customer would wait on the ETH network is at the very beginning when entering the game, so it wouldn't be held hostage to a bloated main chain
