Beat MGS2

The main themes of MGS2 are summed up as

1. Patriot's attempt to mass produce "Snake" like soldiers. Raiden is chosen as a test subject, since in Patriot's eyes, he is a soldier that had no combat experience outside of VR training, meaning a slightly above average person that is digitally trained, which can be replicated over and over in mass amounts of population.

2. Population control using information censorship.

3. And the third parties (like Solid Snake, and Emma) trying to stop patriots from achieving the goal.

The problems start with the fact that

1. Raiden DID have prior combat experience, and Solidus has screwed up the information that is handed to Patriots.

2. Ocelot was not loyal to Patriots

3. Emma pretty much screwed up Patriot's established network structure, but Patriots were able to maintain JD, which will come back in MGS4 as main objective (in the plot's sense).

The story pretty much revolves around the above points I have narrated.
