So many games to finish! Where do I start?

That's not exactly many... I have Final Fantasy IV, V, VI, VII, IX and X-2, and they alone will take at least some 250 hours. At least. Then there's Zone of the Enders: The 2nd Runner, ICO, Star Ocean: Till the End of Time, Kessen, Dynasty Tactics, Portal, Combat Mission 1 and 2, the original Operation Flashpoint and expansions, Delta Force: Black Hawk Down + Team Sabre, Doom 3 + Resurrection of Evil, Ground Control + expansion, Deus Ex, Metal Gear Solid: Portable Ops, Final Fantasy Tactics: The War of the Lions... And probably a few more. And soon in addition to those, Mirror's Edge and Warriors Orochi 2. I guess I'll start working on them soon though.

Now that's a lot.

Anyway, haven't played many of the games you mentioned but I recommend FFX, GoW, and finally KH. You start with FFX, then finish GoW after a break and finally play KH.
