It just dawned on me today that while I finished the original campaign I have never really played or tried the others and I have had this game for 10+ years! Is anyone like me or have you all finished the games single player mode?
I have, and it's got a neat ending. If you die there, it's forever.
Is that hordes of the Underdark or Shadows of Undertide?
I played the original campaign and the other expansions. But, the original Campaign has that deadly final area.
Played through the OC and both expansions to conclusion.
I just got through the part where the howling mob lynches Desther. After that the quests where you get sent to Luskan (I think?) it started turning into a muddle of quests and each time I loaded up I couldn't remember what I was doing in this cave... And then I discovered multiplayer.
I've finished all the single-player stuff.... 894758240985097348758923745 times. I am an addict.

I beat the Vanilla version, but I hated SoTU so much, that I never touched single player again. I can't play single player/ campaign games anymore in general. I need PvP or some type of online version in every game I play now. The only time I'll play single player games is when my internet goes out.
But I really liked vanilla.
I did finish them all! Although I personally think they weren't that great.
You could also play KOTOR1, since that's pretty much the original campaign but with lightsabers.

Beat SoU, still in 2nd chapter of OC. But I'm also playing both of them with my kids, which is a blast.
I played through the single player version before I touched anything online.
I finished the OC and each expansion as they released. But I probably have not touched the campaigns in over 8 years.
I played through the single player version before I touched anything online.
I did the same thing. I played through all three.
