I'm treating this game as "pre-ordered" right now, played through the first 3 missions today and the bugs make it a nightmare to play (as you all know) looking forward to a patch, always good to know people are paying attention and fixing the problems.
The bugs that have annoyed me the most:
1)Where you click on the screen isn't where the game thinks you've clicked - very very annoying when trying to attack things
2)The GUI, much preferred the SH1/2 interfaces, this one seems a bit backwards, something simple such as knowing when the next peasant is available i had to look around for, quite liked the rotating green ring around the fireplace. Also the map is horrible, bring back the SH1 GUI or at least something more similar.
3)"men at arms" ...you direct them to attack something, so they all throw their spears at the same person, when you have 10 of them throwing spears at once person it becomes a bit **** because then they all have to recharge while the AI will happily target different people with different units, killing you all merrily in one sweep. - suggestion: being able to hold right click to attack everything within a small radius would be good!
4) personal preference but i find the zooming in and out system moving between face down and side on a horrible system, just normal zoom in zoom out would suffice.
On a side note, the idea of taking over Britain on a map was much better than simply choosing a level from a list, some sort of interactive level system that you moved through is much better.
You did so well with stronghold 1, i wish you could have achieved the same thing with this

sadly it seems all it'll ever be now though is a bad and buggy game that may one day become a bad bug free game. Drop the name stronghold and don't make a 4th, start a whole new castle game under a new name, use stronghold 1 as the base along with a much much much improved graphics engine and beta test is thoroughly! I look forward to the day something truly worthy of being put in the same class as SH1 is released from you guys
EDIT: You know thinkign about it, what you should have done is simply kept everything from stronghold 1 and kept most of it the same, the game mechanics, gui, etc. then just expanded it, added units and buildings, better graphics and so on, rather than attemptign to completely rework it with new wall systems and in game menus etc.
