Dear Larian, dear all,
I guess this will be "fixed" by Larian soonish after i post it here. None the less, it made playing DOS so much more fun for me and it HELPed a TON in many situation (e.g. see this thread:
http://www.larian.com/forums/ubbthreads.php?ubb=showflat&Number=489086 )
So, on to 360 camera rotation (on Win7):
1) Go to your DOS Users folder (on my PC: C:\Users\XXXXX\Documents\Larian Studios\Divinity Original Sin\PlayerProfiles\<ProfileName> where XXXXX stands for the User you are logged in)
2) There you will find the file "config.lsx". Open it.
[EDIT: if you do not change any options the game will not create a config file]
3) In the file find
<node id="ConfigEntry">
<attribute id="MapKey" value="
GameCameraRotation" type="22" />
<attribute id="Type" value="2" type="5" />
<attribute id="Value" value="
30" type="6" />
and replace 30 with 360.
4) Save the file and start DOS.
Voila, you can now rotate the camera 360.
Dear Larian, I did not find a single instance where i was put off by the models/graphics b/c of the 360 rotation. So, I do not understand why ristricting (or "fixing" the above) the camera rotation at all.

;-)
