Cash flow being the name of the game, what better strategy than to collect monthly cash from people who do not play a game! How do you do that? MMORPG, using automatic monthly credit or debit card charges!

Since it would be so different from the two versions already out, there would be no competition with SH4 or U-Boat Add-on. The resulting cash flow could finance all those other options I didn't vote for.
Hey, it's a business and the object of business is money. Wonder how many people who do not play Runescape continue to pay for months or years before they finally close the spigot? Free money ain't a bad deal.
