I have just received my UK CE version of the game,it comes with game map,two bonus cards(you can type code in game and gives you a bonus item on the ground) comes with usual manual and DVD size hard book (about 70 pages that goes through monsters,skills,feats etc..) bonus DVD (not looked at this yet) plus usual registration and activation card.
First installation was smooth, after that you enter your activation key/details either online or via phone(option to activate later as well) which also went fine unlike my Bioshock fiasco that took 4 hours, they also send you an email reply virtually right away and give you a bonus item(enter the code in game via tile key)for activating your copy of the game(nice wish Bioshock would do that).
I did not need to update my version since it had all the latest patches installed(I did check via the update option).
I have not entered my bonus key items yet so can't tell you what items I received, but will do later ,first thing I did was change res to WS 1680x150 and no AA(I never use AA) plus disabled shadows,controls are set by default to WASD keys so I changed them to the arrow keys for back,forward etc...the game option has easy,medium,hard settings.
I played about 15 mins so this is my initial impressions of the game,graphics reminded me of Gothic 3(think of a game like G3 and Oblivion but not as good) however they were decent enough but won't win any prizes in that department,(nothing special)frame rate was smooth and I did not get any crashes (7800gt ,4GB ram,Vista x64, x2 3800+ cpu).
Funny thing on the box it says XP and Vista 32 bit only but obviously it runs fine on my Vista x64 version too and their forums confirms it will run on 64 bit XP/Vista

.
There are a lot of keys you can customize, you have the usual quicksave, save/load keys etc...the game itself seems big and they have a poor imitation of the Oblivion style map..
I'll keep you updated on my progress and opinions of the gameplay later.
UPDATE: I have played quite a bit more now and still no crashes the bonus item codes I got was a nice sword,armour and shield(very powerful sword and high stat shield/armour for beginner level) the bonus DVD has videos,music tracks and art of Two Worlds.
The graphics are starting to grow on me ,I have not got it on max but I bet it would look very decent with HDR on highest setting,AA on,grass detail slider on max etc..providing you have a powerful video card to run at those settings.
One thing I did do was disable autosave(default is every 5 mins) which gives you a slight pause while saving at that time,quicksave is good enough for me right before I charge into combat,btw when you get killed you get teleported to a shrine with no item or exp lost far as I can tell.
I forgot to meantion sound which personally I find is excellent.I have had the odd pause/stutter that reminded me of Gothic 3,it's not serious however,mob wise they are either too easy or hard ,overall fine by me since you can always bump settings up to hard or easy depending on type of gameplay you want.
Horse riding takes awhile to get use too,the game could do with another patch to get rid of the minor pause stutter that appears now and then,however for the most part its smooth.
