took a look at the website and shop page.
didn't look at the report, but i get the idea from Ashaman73's comments.
2K units in a few days is a quite respectable start.
seems your biggest problem is you're in a rather competitive market.
you basically have three choices:
1. provide the best value to the customer - better than any of your competitors.
2. find another market to compete in
3. be satisfied with what sales you can manage to get.
generally speaking, greater value to the customer = more competitive product = more sales.
value is a function of two things: quality, and price. so you can increase you value by increasing quality and / or reducing price. whats the price of your cheapest competitor who is of at least similar quality? do you charge more than that? if so, how can you possibly justify that, if your product is no better? Your product must be competitively priced.
=== but that's not all that is required! ===
lets assume you've decide to try to compete in this product category, and you've adjusted quality and price accordingly, so now there is no doubt that you are providing a very competitive value to the customer. if you can achieve highest quality product in class as well, all the better, but given your competition, its doubtful. so now that you have your competitive product, you must advertise it.
"build a better mousetrap, and the world will beat a path to your door - but only if you tell them about it!" <g>
at the end of the day it all boils down to a very simple analysis on the part of the potential customer:
"I get X amount of game for Y dollars".
maximize X, minimize Y, tell people about it, and you will do about as well as can be expected, no matter what category of games you choose to compete in.
