I played Metal Gear Solid 2 a few times through, and ACTUAL gameplay was 2 hours. Cutscenes make up about 10-15 hours more. 4 has the same problem it seems. 1&3 seem to at least let you control characters for a while. For all the flak Xenosaga gets for being an "interactive movie," at least you can play for more than 5 minutes at a time. If you can get past the "interactive movie" aspect, the other elements are solid.
