Edit: Thanks for the gold, kind stranger!
Kerbal Space Program
It's the best space travel simulator on the market, although it isn't perfect, if you play it, you WILL learn basic orbital mechanics and gain an intuitive grasp on physics. Saying you're Alt-Right isn't enough, you have to work out your brain, because there are no smoothbrains in the ethnostate. Also, flat earthers BTFO. Get the real solar system mod to make it more realistic once you learn the basics. PM me for a recommended modlist.
Crusader Kings II
Ok, so this is another good candidate. Why? Because you get to play in medieval Europe. You can play as the vikings, you can be an Austrian, you can even play the Byzantines. My favorite part about the game is if you play as a Christian, you can take a loan from the jews, then kick the jews out from the country so you don't pay the loan back. Just wait for a sale because this game is expensive.
World in Flames
This is a really good WWII board game, that accurately portrays the war. You can play as either the axis, allies, or if there are more than 2 players, you can play as one of the respective countries. I haven't really gotten into it, but it is one of the most realistic strategy games I've played.
Pretty much any Elder Scrolls game.
If you ignore that they've been appropriated by bugmen, they are pretty good RPG's. (Before you say that Skyrim is cucked, it's literally a game where if you side with the nords, the nordic leader wants the non-nords out of skyrim, and you fight the (((thalmor))).) Oblivion is the best of the three imo, it feels like a really good central European setting with some Roman vibes.
Minecraft
Alright, look this game isn't really redpilled, but the creator definitely was. Think about it this way. (((Villagers))) have big noses and they are very good merchants ususally ripping you off. Endermen are black, don't swim, steal your blocks, and attck you if you look at them the wrong way. The main protagonist of the game is a white male who immediately after coming into a dangerous world starts building stuff, killing all the threats, and innovating to make his life easier. Notch is most likely one of us, although it would be bad for publicity for him to reveal it. If you want mods I'd recommend better than wolves. It makes the game a lot more of a challenge.
