Ok, I just played through it, heres what I have to say. (Possible spoilers for those who have yet to play it).
Only a couple "bugs" I noticed which aren't really much of bugs at all. My game is missing some meshes and textures from the Breton and Nord armors, is anyone else having this same issue? Other than that, the doors to the last room cut through the wall a little, nothing a small amount of repositioning won't fix, and for some reason whenever someone is killed from either side the Legion Guards start yelling "murder!". I have OBSE which makes the blank dialogue, but its still a little too short for my taste, we should probably find or include a longer silent file. All I have to say on that matter. I also recommend you block rumors and persuasion for the inovolved characters, that was a little strange.
The
battle itself looks good, I played on easy with a god character which was a little short for my taste, but I imagine the fights are a little tougher on harder levels (with svckier characters). An OOO patch with static NPCs that change based on what difficulty you choose would be cool. I wasn't feeling the context of the battle much, a little explaination from Talos or from a comrade would be nice, or maybe a speech before you rush into battle. I understand that he thinks you are someone else, thats a nice touch, makes sense when you think about it though. I find that it doesn't make sense that you must lead them into battle but, really its your choice, and I know this isn't final or anything.
I thought you did a nice job on the modelers house (as FPS hungry as it may be), I liked the little city with little people, its fun to kill them and watch them swarm you.

So I like what I'm seeing so far, all I felt it lacked was a little bit of background information, and those couple little bugs I mentioned, overall it ran fine and I really liked it! Good job!
