A few days ago I installed it once more, and yet again I am completely blown away. I don't think any game I've ever played has this level of profundity, and as I play I find myself mourning the fact that there will never be a sequel.
But, my sadness at the lack of a sequel did lead me to this thread idea.
Simply put, if you had all the technological knowledge and resources in the world, and were in charge of creating a sequel how would you frame it? What would you do with the story? Would you try to have any of the characters resurface? What kinds of philosophies would you enter into the dialogue?
And anything else you can think of..
