Gallstaff, the Metal Gear series and Snatcher do supposedly take place in the same universe. The dates don't match 100%, but basically the events of the Metal Gear series occurred shortly before the Catastrophe. Dunno if that fully explains the names, since I have only played MGS, but Hideo Kojima (the creator of both Metal Gear and Snatcher) kinda ties all his games together like that.
Soldermonkey, keep playing. The story is wicked, as is the art, music, and sound. And the world of Neo Kobe is one of the most fully realized fictional landscapes I have ever seen (just check out JORDAN for a taste). Yeah, there is not much animation, but you canât have everything!
