Stuff
Oh, I see what you're saying now, although I don't see why you feel like you have to make that point. When does any standalone expansion add data to the previous game's folder, other than patches? When does any expansion add data other than patches? If you want to play Age of Empires II with the Aztec and Maya, you'll have to double click on that Conquerors Expansion .exe. On DoW: Considering that the only things from the older games that you could play independently are the campaigns, and the campaigns are specialized and balanced around that set amount of races, I don't really think your point matters. No, you can't go to the original DoW and play the campaign as the Necrons. No, you can't go to the original DoW and play a skirmish map single-player as the Necrons. Yes, you can go to the original DoW and play
against the Necrons in multiplayer if another player owns the Dark Crusade SAE (because the Dark Crusade release creates a patch for DoW to make it multiplayer compatible, so in a way it does actually add content to the old installation folder). I think, but I'm not certain, that you can play as the Necrons in multiplayer through DoW if you have DoW and DC installed. I doubt it, though. It'd make more sense to just run the game through DC.
So what point are you trying to make, then? If you tried to make that point about:
Expansion: Adds actual new stuff, and owning the original or other SAEs just gives you all the original and bonus content at once (so it's not a separate game).
Then I'll just clarify that "bonus content" was talking about the content from the other games that you own and installed (or duped the .exe to fool the game, if you're like that). That is, if you own Dark Crusade and all of the previous games, you get access to all of those other races + special units unlocked from owning multiple titles from the series. "so it's not a separate game" was talking about something like Sins of a Solar Empire: Rebellion, where it's a "Stand-alone Expansion" but it's really just a new game. There's no synergy from owning the other titles. It's new, improved, updated. It's more similar to a remake except it uses the same engine and there's not enough stuff to actually call it a remake. The game is its own entity, it's just called a "Stand-alone Expansion".
That's different from the DoW and CoH SAEs which all inter-relate.
Also, look up "fallacious". I don't think that word means what you think it means.
Damn, got me there. I've only known it as a synonym for false, didn't think it was actually a special case of false. Anyway, I retract that since I understand what you mean now, but I still don't understand why you try to make that point.
