After spending ~50 hours with Samurai Warriors 4, playing all story maps and seeing most of chronicle mode, I have to say I'm kinda disappointed in it. Battle system is some of the best across all musou games, but everything else kinda falls flat in the end. Story mode, while extensive, never really manages to feel epic, engaging or coherent, it's more a really fractured retelling of a warring states summary. Chronicle mode was an interesting idea, but it lacks huge amounts of fresh content to make the extensive grind bearable. The greatest detriment to longetivity however is the weapon system. Less skins, limited modification and also no real incentive to build an overpowered character, since the game is rather easy and lacks interesting post-game content.
It could have been great, if the usual Xtreme extension were to build on what is there, but with 4-II being more of an alternative version (although adressing some problems) there is quite a bit of missed potential. Maybe Empires will do better.
Still unsure if I'll get Pirate Warriors 3 on release day. I am looking forward to it, but waiting a week or two will probably save me a few and I can finish Bloodborne in the meantime.
