I like Splinter Cell. No, I love Splinter Cell, but MGS still holds the number one spot in my heart. I love that franchise. Where your argument loses its ground is they're entirely different games, and you're using that to fuel how one is better than the other. SC is grounded in a realistic world where everything is logical and possible, while MGS is more of a fantasy game. When I want to feel like a badass, stalking people in the shadows I'll play Chaos Theory, if I want to have a cinematic game experience I'll play MGS.
