I did not understand nothing from your post!
Does the game, 3 all, work like the original disk versions?
Not exactly, no. The originally published 'Civ 3 Complete' collection allowed players to use any of the 3 versions of Civ3, as they preferred:
- 'Vanilla' base-game (patched to v.1.29); 16 playable Civs total; executable file = civilization3.exe; ruleset format = .bic
or
- Play the World expansion (patched to v.1.27); added 8 playable Civs (= 24 Civs total); executable file = civilization3X.exe; ruleset format = .bix
or
- Conquests expansion (patched to v.1.22); added 7 playable Civs (= 31 civs total)*; executable file = conquests.exe; ruleset format = .biq
Each version ran/runs from its own executable file, installed in the relevant game directory. However, as with the Steam-version, the GOG-version
only includes the Conquests v.1.22 executable: it doesn't include executables for the 'earlier' versions.
All the original Vanilla and PtW assets (music, leaderheads, units, etc.) are included, because the Conquests expansion (using the conquests.biq) will not work without them: it was designed to be added to an existing Vanilla/PtW-installation, so did not itself include all of the earlier content. Unfortunately, in addition to some fairly major rule-changes (e.g. corruption, Army-stats), the conquests executable also contains some bugs that don't occur in Vanilla and PtW (or rather, that were patched out).
The ruleset-file formats are forwards-compatible with the following version(s), but not backwards-compatible with the previous version(s). The Vanilla 'civ3mod.bic' and the PTW 'civilization3X.bix' (and also the respective Editors)
are included in the GOG-version, so it is
technically possible to play a 'Vanilla-like' or 'PTW-like' game using the GOG-installation -- but to do so you must open them using the conquests.exe.**
However, due to the abovementioned rule-changes from Vanilla/PtW to Conquests, the earlier versions will not play exactly as they did/do on a CD-based version.
