How about a different pattern;

• Figure out what your breakeven is - in other words, how much money you need to make to recoup salaries, licenses, and generally keep the lights on.

• Put out a free demo (and I mean free - no DRM either). See how many people download it within a month or so.

• Project the production budget for the next game.

• Price based on a 2% retention rate of the demo downloads to accommodate breakeven + next game + 5% profit for op-cap.

Rinse and repeat as necessary.
