Disappointed that it took that long for MGS to come up, and no one even mentioned MGS4? What the hell. Of course MGS3 had the best final boss, but MGS4 had a pretty god damn awesome final boss as well. MGS1 and 2 did as well, but less so.
Other than that, I more or less agree that final bosses usually aren't all that good, but it's understandable. They're the last hurdle to tackle before the end, and unless the game is all about the gameplay, you're really just wanting to finish the game at that point, so it sucks to have a really tough boss that takes several tries to beat. But then it's also sad to have a boss that isn't really great in any way. There has to be a good balance that is VERY difficult to achieve. Yet Kojima somehow managed it with four games, so maybe game devs should take some lessons from him.
