Hmm.
I've restrained myself to comment on any aspect of oEtG so far, mostly because of the clear division of opinions among the community. I'm in no way professional in legal matters (wish I were.. damn!). but apart from that and my personal opinion on the matter, let me ask you this:
If you had the energy, and the resources to create a project such as this - which is no matter how you look at it, a spinoff of a game already existing -, why didn't you try to make a purely standalone and genuine game in the first place? If your intent was to keep EtG, or its forums alive with this action you took, you could've put up a simple PONG game on Kong even, and expect the same result or outcome. Now, this may be a harsh example, but think about it. This game is dead currently, or maybe just slowly dying, but putting up an alternative for it may encourage some players to spend more time off the original to explore, or even to get fond of some of the extended possibilities in it.
That said, my thoughts may be powerless here, considering I have minimal experience or interest with oEtG, and for every passing day, I feel less and less urge to load up the original even.
