I think cartridge-based video games and surf music have a lot in common, having to impart feeling without the aid of vocals and having to do so with a very limited set of sounds available. Going even further than that, surf often tries to evoke a sense of danger and adventure, which is very familiar territory for video games. The themes that stand out in video games stand out because they're great: you're usually going to hear them on a loop, often for hours, so if you still like them after you've completed the game then that's a feat.
