I agree with the whole thing, except for the replayability. I didn't find much replay value in the game, collecting camo didn't appeal to me since I already finished the game (plus I didn't want to bother trying to get The End's =\). The random secrets in the game were fun, though (especially the transmitter cutscene extra

). Snake vs. Monkey's pretty fun, too. Replaying the game on different difficulties didn't appeal to me, though, since the main reason why I play any MGS game is the deep, twisting story.
Well, anyway, just my two cents.
btw: MGS:3 has the best ending out of all the MGS games in my opinion, although I can't remember what hapened in the first game.
