Assuming said programmer wants to create PONG and BREAKOUT styled games... Simple idiot platformers... and everything you could do in Blitz with just a little more effort and imagination!
Ironically, the folks at the TV3D forums feels the same way with people who use Blitz, 3DGamestudio, DB...etc.
But the point is that they were actually able to make a game with it....and less than half the time it took wih Blitz...just using a few mouse clicks. Would gamers/end users really care what it was made in?
