Classic XCOM is really fun imo, but it does suffer from some quality of life issues. It's possible to fix some of that with mods though and imo it still holds up. I've definitely put more time into the reboot of the series, but the original has a grittier feel, a bit more "open world," where you're gonna miss UFOs and you're gonna have to cut and run sometimes, and there's also a lot of exploits and tricks you have to figure out on your own (intended or otherwise).
Xenonauts is a more direct remake and it's good, more balanced and polished, but when I play it sometimes I just say, "I'd rather be playing old school XCOM." Hard to put my finger on it, and it might just be that I already know the tricks for the original, or that the jankyness makes it fun. Xenonauts does hold up on it's own but it's hard not to compare the two.
Generally games have gotten better but I'd say there's a handful that have withstood the test of time (especially with basic UI improvements).
Historically, you're completely wrong.
Hitler came to power with the support of capitalists (here meaning "people who own substantial capital" rather than "ideological supporters of capitalism"). They saw him as a way to maintain order against socialism and to break the power of unions. A similar story happened in Italy, and in other fascist countries.
Many capitalists did in fact benefit from fascism. There's some confusion about fascist economic policies, but you should know that the term "privatization" was first coined to describe the economic policy of Nazi Germany. When they nationalized companies, it was because they were minority owned, and often they were redistributed upwards to the capitalists.
Labor rights suffered tremendously under fascism, with labor organizations exterminated, allowing capitalists to impose much worse conditions, lower pay, and longer hours on the workers, as well as using prisoners for slave labor. Any attempt to challenge these conditions would be considered treasonous, undermining the war effort.
Even when their countries were defeated militarily, many capitalists got off scot-free. For example, the pharmaceutical company Bayer (which merged with Monsanto in 2016) was once a part of IG Farben, which manufactured Zyklon B for the gas chambers. After the war, Bayer rehired Nazis to high level positions, including for example Fritz ter Meer, who had been on IG Farben's board of directors and became chairman of Bayer, despite being a convicted Nazi war criminal.
