Thanks for that informative post WhoCares.

As for me, I finished the main storyline today and I was pretty satisfied with the ending. I'd say it was a mostly happy ending with some caveats. The final phase of the game really made me think and at times I felt like I needed a Ph.D in metaphysics to really grasp what was going on.

For my second playthrough I think I'll go the "street kid" route and play it more "Mr. Tough Guy" instead of being "Mr. Nice Guy" all the time with my decisions.
