Thanks for all the great feedback everyone, I really do appreciate it. I tried to put together as much video and screenshot footage as possible because I know exactly what it's like to sit around freaking out until launch day comes. IGN doesn't offer me anything extra for any of the extra effort, it's all for you guys.
@Walker, the link has been fixed thanks for pointing the issue out to me.
Oh yeah, a lot of siege battles including several on Kyoto. I had to defend against seige many times as well, and while a lot of people might be quick to dismiss castles as being nearly useless in Shogun 2 they're really not. The lead time you get to rain down arrows, firebombs, or volleys of matchlock fire is huge. By the time the enemy starts crawling up they're going to be down on numbers with morale issues as well (especially if you have fire arrows or matchlocks).
I did not use archer walls really only because I read that they were considered exploitave. I just made sure to have some spears handy if cavalry was around. The only lag I saw on occasion were minor hiccups when an in-game cinematic would first pop up, but it was over within a second or two. I only tested the game on one system, but this same system has seen crashes in other Total War games.
I played the game a LOT. I wish Steam could tell me, but since it's a review build it doesn't log time. I played through two full campaigns, 8-10 custom battles, all the historical battles, and many hours of multiplayer. I wanted to make sure I saw everything before I wrote my review.
I really had no findings on lag, and crashes were limited to a couple of instances in the campaign multiplayer only. Even then I was still able to play out a full co-op campaign game and take kyoto with another editor without seeing a crash. Avatar mode had no issues. It's the only reason I docked 1/2 a star from the game, otherwise it's one of the few games I'd actually consider giving a 5/5 to.
This should be the game yes, hopefully the majority of lost fans will be willing to trust reviewers and come back. If not they're going to be missing out on an excellent TW game.
