The one that reads that they won´t ever charge for an expansion / DLC of any game sold here and I was thinking, for example (well, mainly) on the EA games. I mean their price is so low and it would be reasonable, or at least I think so, to charge a bit more more to reach 9,99 $ if you want the expansions.There may be some exceptions, like the "Deeper Dungeons" (I mention this one because I played it) because you can´t charge 3,99 for a mere (and short) collection of maps. But with some other expansions like "Alien Crossfire" I find it reasonable (Well, with this one I don´t see as bad even to charge the full 5,99 price just for it because it is so long and deep as Alpha Centauri itself).
I await for your responses!!!

Edit : Title correction : Should GOG break one OF their "we won´t, never" taboos?

No. No way. That would be setting a too dangerous precendent.

So charging SpellForce 2: Dragon Storm for 9.99$ and Jagged Alliance: Deadly Games, Jagged Alliance 2: Unfinished Business and Jagged Alliance 2: Wildfire for 5.99$ each doesn't count?

Nope

Those are all standalones. I think Tejo was talking about expansions which require you to already own the base game.

Rather not. I like the way things are right now.

If push comes to shove, though, I'd just have to adapt I guess. Doesn't mean I'd like it.

JA games were relesed when gog opened the store, so they may have some contract obligations, but since Gillaume told that they were in favour of not charging more for expansions, they never did that again, even with "standalone" games. And there is also another problem... Some expansion´s rights may be owned by another company, and most publishers won´t like to share their profit on the original game.

Hey... They already did.
It's not Good Old Games anymore. It's just GOG.com ;)

I don't really care what taboos they break if, in the end, they stay true to their customers. So far so good.

No way.

Agreed.

The only issue I see with adding DLC and expansions you can pay for is that you'd have to be aware of wether or not you can use it. For example, setting all expansions into their own list and making clear that it will only work with "Such and such" title, plus instructions on how to use it if it's being purchased for a game that they already own on disc. Otherwise we'll end up with some annoyed people over buying content they can't use. On the other hand, it might also be a bit of an annoyance trying to get the DLC accepted into a folder for the game itself without confusing anything. And I'd hope that nobody tells me that won't happen, we still get new users every week and there's no doubt from any of us that some of them are rather limited in what they know or understand of computers, let alone understanding that an expansion of content is not the same as having content to play by itself (Someone I think mentioned this isn't always the case, but still)

I guess in this instance you might as well list a game twice, one with and one without the DLC with a separate DLC only list for experienced users that sign a consent form or something if they want to try to get it working on a pre-owned game.

Bundle them for free with game or sell - I don't care. Just add them to GOG catalog.

One thing they could do is grey out the 'buy' button if you don't have the base game on your account. Of course, that would block people who have the base game on disk and are just looking for a DD of the expansion.

I think it's better to stick with complete game versions and standalone expansions. At least you know you know that you get the whole thing when you make a purchase, and don't have to dig around for every single piece of DLC, that got released or will be released.
