I see where your coming from you have great thought behind it we just don't agree, much like I don't agree with my wife sometimes.
I personally believe more companies should stick with the same engine and make new games with it, or improved sequels/expansion packs (like ODST) because it saves companies a lot of money. Maybe KOEI was onto something for once with all those dynasty warrior games!
We constantly see companies post losses (Unless your name is Nintendo) but if they were less ambitious with their engines by not upgrading them so much they would probably see more of a profit.
I know that will hurt the graphics lovers out there, but someday your company has to land a profit and it should be through innovation and improvement in game play rather then eye candy to help save costs.
It's just that simple.
