Kirben: Why so excited? these games have the worst path finding I have ever come across, poor AI and the second game is completely unbalanced. I doubt GOG was able to fix the games without source code either, so expect completely random crashes back to the desktop too.
Nirth: Ouch.
Anyone with the GOG versions that can add their views on these issues?
I have never had problems with the pathfinding, in this version or the original. The units will always find their way. If you make the walk over a long distance by themselves they might choose the path with more perils/enemy troops, like in most RTS, if they calculate that one as being the shortest.
As for the AI: unbalanced as in dumb? Smart? Overweight?
Bottom line is you buy this for the nostalgia, maaaaan.
If that's not the case: it was a "B-movie" RTS back in the day that couldn't hold it's candle against Red Alert / Warcraft 2, but the setting and units were uncommon, as well as the base management. It also had hero troops with abilities and unit experience before other titles. You will end up repeating missions fairly early on as the difficulty can stack up; it's the kind of RTS where every unit counts (think something similar to Original War), so getting in a firefight with even a few disadvantages can mean a crippling defeat or a minor victory that will make it almost impossible to finish the mission.
Still, it's awesome, maaaaan.
