By that point I will go as far to state that Panzer General is, in fact, an RPG.
It has C&C up your ass, more profound C&C than any of the RPGs ever. You get major in Warsaw, you go to Norway. If not, you don't see this map ever. If you get major in France you get to Sealion40, and there you can knock out England out of the war with another major. That is, you will never ever fight British again in that campaign. Overall, the campaign progression is quite nonlinear, with your performance deciding the course of the campaign and sometimes overall choice.
It has stats. Each unit has initiative, movement, offensive and defensive stats that directly determine the usefulness of unit in combat.
It has experience. Unit gain experience through combat, and experience levels are crucial. Five star FW190 rips and tears through enemy aircraft while zero star FW190 is way less potent.
Everything is decided with rolls. Units roll for initiative, roll for misses, suppression and kills.
There's no "build" for each unit, but there are builds for your core army, similar to party composition of party-based RPGs. You can invest heavily in airforce, tanks or artillery and this will shape up your offensive or defensive actions. It's just that instead of paladins, wizards and clerics you have tanks, artillery and aviation.
It has no dialogues, but who needs that shit? Storyfags?
There's no loot, but you gain prestige by capturing objectives and destroying enemy units and this prestige is used to purchase new units or reinforce existing ones.
And oh boy, there's Panzer General 2 that has even more of that, for example, special abilities gained with level-ups - read "perks".
Am I serious? Decide for yourself.
