I think that the developers/publishers/whoever should have made it perfectly clear that this edition of Doom, Doom II, and D3 is not compatible with mods.
I specifically bought this so that I would always have a legit copy of doom.wad and doom2.wad, so that I could always edit, from anywhere in the world. Should I have looked after my original discs a bit better? Of course. But that isn't the point here, is it? Just like how D and D2 are supposed to just be bonuses - not the point.
Because I am not even able to play the apparently-finally-finished version of the Classic Doom remake (Ep1 at least) for Doom 3.
The game *does not do what I bought it for*, and I SHOULD be able to return it or swap it for the Steam products that actually deliver the editing-friendly products I THOUGHT that I was buying.
Sure, I can buy the other versions - but I don't know if THEY work for what I want now, do I? Because there is no indication of this type of thing before you buy, is there?
And frankly, that's just bad form.
