How much are you prepared to pay for such a game???
how much will it cost to make this game???
how many copies do you expect to sell??
well the avage compuer dev cost is = $28 million

SH4 sold 50k
http://www.subsim.com/radioroom/showthread.php?t=161973 (post #3) so lets estimate you new game will sell 50k also.
28,000,000 / 50,000 = 560
then there would be other costs involved (disturbution, taxes, store profit etc.).
Are you realy goning to pay around $700 for this sub game???
and at that price i doubt that you'd sell 50k copies pushing the price even higher.
