Snatcher

Hideo Kojima is a man best known for the Metal Gear series which spans more than 20 years since the original MSX game. It is by far the best game series of all time. And then, I played Snatcher, which impressed me equally as much. Note also that the Sega CD version is the only English version of Snatcher (I think there are fan translations for the original though).

If you have seen "Blade Runner", it is basically a rip-off. But also a very good one that takes elements from other movies such as "Terminator". You play as Gillian Seed in an organization that hunts down "Snatchers", a robotic life form that takes over the victims body. I won't tell you anymore than this, otherwise it might spoil the game for you.

Gameplay is almost entirely done through choosing actions through menu's (with the exception of a few shooting scenes). It is similar to a point and click adventure, just without all the pointing :P Sound and music is one of the awesome things about it. Long before Metal Gear Solid came to show how voice acting is meant to be done, we had Snatcher! Fantastic voice acting that I believe could even surpass Metal Gear Solid! Music is chilling and atmospheric. High quality too, due to the Sega CD technology.

In conclusion, if you are a fan of Metal Gear Solid and it's story features, you will truly appreciate this game. It is hard to find and valuable for Sega CD. But that's why we have emulation, figure it out yourself... As said earlier, this has a lot of things copied from Blade Runner, which is also a great movie, so see that as well.

If you are trying to find a good cult game that doesn't suck up to the masses (coughhalocough) then get yourself to play Snatcher. It's one of the greatest games you'll ever play.
