Let me start off by saying I am not suggesting that CIG ever build any games other than SQ42, SC, plus AC and SM. But one thing that others have pointed out is that they have developed an extremely impressive set of core technology and tools that could be licensed to other game developers...so the question is what would you like those other games to be? My personal choice would be a non-franchise superhero game. I miss the now gone City of Heroes franchise. Being able to play that on a planetwide scale with multiple cities and a whole seamless planet is very enticing. Another would be a planetary scale Call of Duty persistent universe game with ground, air, and sea operations all at the same time.
