Single player game,
It was a ps1 or ps2 game, Strategy / fighting game, you had your dinasty (if we can call them so), you had to conquer outposts, everytime you did a "Move"(like conquering, or sending troups), the whole world would react, sometimes you had to fight, the game would then, change style and become a fighting game ( 1 vs 1 if i remember correctly, and it was an arena it was not 2D like street fighter ), if you win, you would conquer the outposts otherwise you would just lose troups (not sure though).
it was an oriental based game ( i think japanese? ).
if i remember correctly, you could buy things ( not entirely sure )
TL;DR
Single Player.
Ps1/ps2 game.
in the "Strategy" mode, it was a Map, with a bunch of outposts, you could conquer them.
Strategy/fighting
Strategy because you could choose where to send troups (With troups i mean Warriors)
Fighting because when you did a move, im pretty sure you had to fight, and the game changed to a fighting game.
Pretty sure it was an historical game. (no weapons like guns or something like that)
Japanese style ( or oriental in general )
You could move your troops to start a fight, after the fight started, the game changed to a fighting
type.
Enemies could conquer you [not entirely sure, but i remember that your outposts could be destroyed]
pretty sure the game is around the age of 2000 to 2011.
Thank you all!
