Since this problem isn't new (several editions don't allow to install Gothic II without add-on), a WoG community member created the Gothic II Classic-Mod
. Due to engine changes in Gothic II: Night of the Raven a 100% conversion isn't possible - but it's very close and new/hidden features (like quick-save/load) aren't that bad :)
The "international" version "2.7 (eng)" doesn't support modifications (by intention/design).
Step by step to get it running:
(1) install Gothic 2 Gold Edition
(2) in [gothic2]/_work/Data/Scripts/CONTENT/CUTSCENE
make a copy of Ou.dat
(3) in [gothic2]/system
make a copy of Gothic.exe
(4) install the "report" version
(5) install the GothicStarter
(6) install the Gothic II Classic Mod
Now you can use the [gothic2]/system/GothicStarter.exe
to launch the Gothic II Classic-Mod or Gothic II: Night of the Raven.
If you want to directly run the Classic-Mod you can create a link to the GothicStarter.exe with the following parameters: -game:G2_Classic -start
ps: same procedure for the German release (setup_gothic2gold_german_184.108.40.206.exe) - but you skip step (2) and (3).
