If not, I highly recommend it. It's a lot of fun as a pure puzzle game, but the entire story appears to be an excuse to do a bunch of marxism. It's full of dialectical materialism. It's got Lenin quotes. It's talking about how material conditions shape history. It loves talking about power and how it's not inherently bad and it should be wielded for good.
I haven't looked into who wrote it (I should), but I can almost guarantee they're some sort of marxist.
Can you believe the developer who makes Serious Sam developed an incredibly communist video game?
Yes, this was frustrating. My partner just played the original a couple of months ago (I played it when it came out and loved it) and we both were a little frustrated and the story fell a little flat by today's standards.
