similar to Shoukoku no Altair and Kingdom, i really liked their strategy planning and style

Maybe Sangokushi?

i'll put it on my read list but any other recommendations with better drawings? Sangokushi , the characters kinda look amateurish.

I haven't read the 2 you mentioned, but if you like strategy with a military focus, I can recommend: Bokko. It follows the siege of a city in ancient China. I thought it was pretty good.

I recommend Imperial guards but be aware that it’s just an adaptation of the first books of a novel. Only 34 chapter but it’s awesome.

Ad Astra - Scipio to Hannibal
Arpeggio of Blue Steel maybe
Chang Ge Xing
Ginga Eiyuu Densetsu maybe
Gunka no Baltzar
Historie
Master Keaton maybe
World Trigger maybe

I read that long ago, was a good manga, too bad it was too short ? but thank you for your recommendation, will reread it later on just to freshen my memory
