I have already talked with tf2honeybadger and asked him about the progress of the CKG (in-game gold) <-> XMR listing. He confirmed that it is happening. I have also heard this from the Crypto Kingdom people as well, so as far as I am concerned, there will be a medium of getting money in and also out in the near future. My statement was meant to imply that I would keep the XMR in the game even after that bridge to poloniex is implemented.
As far as things being pegged to XMR, they are being pegged to XMR because the plans for implementation of a CKG to XMR listing is nearly complete. I don't know about you, but if something is assumed to be having value soon, wouldn't it make sense to discuss it with that value attached to the items? Just because the tech isn't 100% complete doesn't mean the in-game assets are worthless.
Right, you will eventually be able to trade CKG, which is what I said; you can trade the virtual game items freely with other people. But you are trading it with other players, you are not converting game items back to XMR through the game. The developers have no obligation and likely won't trade back the XMR they earned for virtual game items.
Every time the developers, i.e the "king" sells stuff, land, titles, whatever new content there may be, the "real" money, i.e XMR is siphoned off from the game.
I find it hard to explain my point through text, but CKG is not pegged to XMR just as USD is not pegged to gold. Just as the government can print USD whenever they want, the "king" can "print" land, titles, new content etc, and in all likelihood CKG's value will go way down compared to XMR in the long term.
EDIT: If we assume that X amount of money will go through the game in its lifetime, then the amount of money IN the game will tend to 0 as T tends to infinity, because money that goes to the king is sunk.
This is compared to if CKG or moneritos was really pegged to XMR, ie. there's a way to trade it back from the king/devs, then X can pretty much stay constant (minus a % fee for the developers), then your property/CKG/moneritos etc will be able to keep their value.
EDIT2: Again, I plan on playing the game, but my main point is that the game is just a game, like any other game out there designed to make money for its designers, with possibly the side effect of helping monero become more known.
Right now, it is really trying to advertise itself as almost a sort investment, which it simply isn't. I know, in the game thread they did say that its just a game and all that blah. But the rest of the post and posts after it really downplays that point, and tries to entice people by saying how xxx is worth thousands of XMR. I'm not really comfortable about that. It's like a scam company putting in a little fine print and continues to try to trick people.
