I’d say the lack of retro and pre-2010 gaming discussions is partly because of the novelty and the relatively small size of Lemmy. Since it’s small and a sort of direct competition to the already-massive Reddit, Lemmy users sort of self select. In other words, it’s generally people who care about FLOSS or federation, anarchism, privacy —just to name a few of the things that I’ve seen a lot of here.

But that does not mean at all that those are the only kinds of topics that you’ll find, nor that new kinds of discussions are possible! As other users have suggested, go ahead! Create your own community! Or join an already-existing one and talk about your interests! You might be pleasantly surprised!
