As a long-term veteran (at-least 5 years hurhur more like 10 years if you get the obvious reference) This only contains the original with the 3.1 official patch. Meanwhile I have the actual CD's from 1997, the soundtrack CD sounds great, but does not suit the game what so and ever. Though soundtracks from C&C Tiberian Sun suit's so much better. But for the boring original gameplay, not good, unit path-finding is ancient, Zero has far better path-finding though that mod is very basic and lame compared to Excess 131. This GOG version is... ok considering Cavedog is dead and being the best RTS with over 40 awards since launch, better to get this for free with mods too make this "retro" experience so much better.
