I completed the main quest earlier today but only thanks to the LAA patch floating about, as the game was chronically unstable out-of-the-box and even after the latest patch. The game was crashing after less than 10 minutes, yet apply the LAA fix and I've just completed 4hrs without ANY issues. I know Bethesda are working on a patch to add LAA support but I'm very disappointed, as I never had any problems with Oblivion out-of-the-box.
As for the comments, I do agree that it sounds like gameplay tweaks or fixes - stuff that really should be for patches. That's probably not what they meant but I think they have to tread very carefully. Saying that, I'm really interested to see what they do. I just hope the content is more interesting than the Imperial / Stormcloak plot line, as it was tedious as fuck with every mission being "talk to A; attack B; go back to A; attack C; etc" - absolutely no originality. Not only that it was deeply broken, as I didn't get one of the achievements (one that was impossible not to get as I completed later missions) and my brother came across a bug that completely broke it.
Keep working on new content but the game really does need a lot of work. It's a very good game but it did start to get very samey the further I go in and the dragon battles are pretty underwhelming.
