Looking into it further, you may be right. It looks like in his younger days he was more vocally socialist and pushed harder for more immediately and obviously socialist ideas but tempered that at some point, likely to make himself more appealing to win elections. Some people claim he is not a real socialist regardless because he is reformist.

Yeah I was just clarifying that Bernie is not a democratic socialist himself, he just misuses the label (although that misuse is more common than not nowadays)

He claims democratic socialist, but his stated policies are social democrat.

Can confirm at least Stellaris works

Steam’s Proton (the tool that makes windows games work on linux) works on pretty much all mainstream distros, you can just install a desktop linux distro and intrall steam on it
