Realpolitiks, an odd Polish-Russian (?) grand strategy game. It suffers from a clunky interface, rather questionable game mechanics, lack of any difficulty sliders (even Paradox has them, ffs) and other bad things, but it's the only new more or less playable grand strategy game about modern times right now.
Geopolitical Simulator games are utter trash, ancient SuperPower games suffer from stupid AI and bugs unfixed since 2004, Supreme Ruler games also have shitty AI despite numerous expansion packs and sequels, and on Paradox side there are only unfinished mods for Hearts of Iron. That's terrible.
