Siege weapons and engines do not work. The ai will leave them unused causing an ensured defeat. The taking of castles is at least 15-20% or more of this game. Since you cannot effectively participate in that this game is only 80-85% complete in my opinion.
Furthermore, there are nerfed factions like battania that make playing that faction like a handicap. Doesn’t matter that you have the best archers because Valandian cavalry can overrun you and kill everyone, even when you have high ground.
Enemy armies can quickly replenish forces despite your seizing of many of their castles, towns, and notables. Defeating a 1,000 strong enemy force only to encounter another in two days does not make the game fun but only an annoying grind.
Would highly recommend you do not purchase this game and spend your money on something that benefits your leisure time.
