Amazed you managed it in BlitzPlus. What database did you use?
Oracle. It wasn't really too bad tho' although I must admit I did have a few "I should've @#!*ing done this in Java" moment. Seriously though, 21 months away is a lifetime in terms of computing / gaming, I hope your "projections" are accurate.
They're not my projections, and 21 months is a fraction of the time it takes to make a game like this.
