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?
I had not considered this angle to Croteam, but that's a great point.
Yeah, they're basically a bunch of dudes who got one of the last socialist educations in the Soviet Union and were suddenly forced to interface with the West in their terms. Like Serious Sam only exists because they weren't allowed to sell "stolen" code for a soccer game clone they made. So they copied ID and made their own engine for it.
