On the boards I visited, it seemed pretty mixed, I noticed a lot of liberals playing both the single-player and the big competitive ones too. In general it just seemed like the left took over the gaming industry.

Conservative and MAGA voices would get drowned out. Lefties would be screaming and crying and screeching in threads about "right-wing trolls ruining the board", even though the right-wing posters were generally more civil and low-key. But I guess that's how it is on most social media, not just the gaming world.
