What you are looking at is my China Playthrough of the PRC that I.. had 'fun' with (used console commands, because I barely understand HOI4 that isn't LARPing as leftists and gaining super weapons lol) This is in The Fire Rises Mod right here, that features cool and weird paths and allows for these fun stuff to happen. What you see is just the beginning btw, because this: 
is what I ended off with before I went to bed. Took me like, 6 hours, honestly, and I need some.. break from HOI4 afterwards, because being this obssessive over moving units around does not make for good creative work, but if you want, I can like... add more screenshots of the Americas, or Europe if you're curious on how that went.
Maybe? It really depends on how you play and what you want to 'cheat'. For example, I am a LARPer at heart, as I'm a hobbyist creative writer, so I make my army have like super tanks and futuristic air planes or something, because even with those I find myself struggling yet knowing I can do some bullshitting to get my roleplaying good.
For example in the same game in HOI4, I fought and sent some volunteer units in a French Civil War supporting the Socialists against Fascists and Liberals, and there were a lot of times where my AI nation would fail me and make me retreat, or get surrounded or pushed back, so I had to think while RP'ing that Chinese Tanks that are the pinnacle of humanity still struggle if the country you're supporting is weak. Though, for that one I had to bullshit my way and get a focus tree for it because the USSR won and to make the game 'interesting' the fascists automatically rise out of a Europe devastated by it, and the Socialists were restricted from a path and are just there to get crushed by the Fascists.
From what I remember, there are economy cheats (like the income_var/liquidity specific to The Fire Rises Mod), research and army cheats (specifically only technology, you'd need a mod for actually creating units out of thin air), political cheats (this one is harder on mods like TFR, but you can usually figure it out if you remember how to connect the default vanilla commands with the new content of the mod), game rule and paths cheats (for example, you can set Russia to go USSR in the TFR mod, without you having to pray to rng god or disable volunteer limits, wargoal limits, etc.) and focus tree / decision cheats, where you can use
ffto do whatever you want with them in HOI4, anddecision.nocheckscheats to bypass most restrictions on that front.That's for HOI4, though.
