Well, I've been collecting Metal Gear for the past 9 years. While I can't claim to have "everything" (and I certainly would not want to), I can say that I got all the figures, even the rarest of the rare. You won't find things like Metal Gear NES or Snake's Revenge in this collection. I mostly stuck with the Kojima games and a few others. In any case, here is my humble collection:
With the release of MGS4 I'm finally finished with the series. My collection contains all that I'm interested in getting at this point. Granted, I will likely pick up any MG1-MGS4 figures that they may make in the future. However, I don't see myself collecting anything from any future games.
Well, for extreme Kojima stuff (and I do mean extreme) I think both the Sega CD version of Snatcher is called for (once again: it's the only way you can play the whole thing, both officially and unofficially. I mean, if there was a turbographx fan translation, you would surely see me owning that one, and not the Sega CD version, ). The good thing about Sega CD Snatcher, is that right now Sega CD emulation is so perfected, that you don't need a Sega CD to play it anymore.
Of course, I love playing it on my Sega CDX, but still, in all due honesty, for the exception of the lack of Light Gun in emulation, the game plays 100% the same in a decent PC with an emulator (I posted the links in the other tread) than on the Sega CD.
Also, you're missing the Solid novel.
Been here longer than I expected, I can tell you that...
