Hey all, inspired by cryptokitties we set out to make a more complex game, but one that also had a great focus on the UI and making it fun.

I'm happy to answer any questions about web development, ethereum development or any thing else!

If I buy it can I resell it soon for more money :^)?

You're asking 95 USD (and going up) for a DLC to a game that is not even released yet?

The FAQ[0] says:

All I'm seeing at https://github.com/EtherBots is a Solidity contract.

So this is a collectible game where only 3900 people get the initial supply? What if I wanna play it later, will I have to find someone willing to sell it to me?

Hmm, so everyone's going to think "hmm, everyone's going to think, 'hmm, Ethereum went up when cryptokitties came out, perhaps this means I should buy some Ethereum now,' so perhaps I should buy some Ethereum now," so perhaps I should buy some Ethereum now.

I think they answered it by putting "cough lamborghini cough" above the second instance of the "Buy Robots" button.

At least, well enough for the SEC to take an interest.

My wager is people are fixated on coming up with an addictive killer app that at least guarantees ethereum will stick around a bit for the app alone, regardless of ethereum or the value of ether.

That certainly looks to me like the "random" reward is just based on the previous block's hash.

More issues:

- Rarities of each part is not encoded in the contract (It just depends on how the application logic decides to decode the uint). They could swap Shadow parts with Gold and the contract doesn't do anything to prevent that

Since this is a comment, if 23 is generated, a unit will be generated, which they _promise_ will be a lamborghini. Pinky promise.

There is also nothing stopping them from bumping the drop-rates for the final game. They promise 2%, but since this contract is void post the pre-sale, it will have to be a new one and it could have a 80% lamborghini drop rate!
