But the game has existed for ~48 weeks already!!
That is remarkable. Congratulations on the upcoming first birthday!
When the game was 2 months old, the Long Bond auction (now item_id "LB1615") showed the interest rate of 300% for a realyear. Clearly that was realistic for a project just started, and projecting 6 times longer to the future than it had existed!
Now whether we settle at 72% or go to 60% or 50%, the next year there will be laugh anyway. Either to how easy it was to get free money, or how silly people were that it could be paid back.
But personally I am too busy in developing the game to have any thought that it might fail...
Once it's at release version you have to get someone like totalbiscuit to review it. You can actually pay him to review it (ideally you wouldn't have to but as a contingency) but he is explicit about being paid when he does paid reviews and it doesn't appear to cause any bias. It would probably be well worth the investment if you are confident that he will be impressed, hes a harsh critic if he isn't. Exposure like that will be key to its success because a game like this is probably going to be quite dependent upon a strong network (of users, not like servers).
Another reason is that video game journalists are notoriously extreme radical left. And the left hates free markets. So you will be very unlikely to get publicity from them.
