Either this is an incredibly important update that will haunt me until I figure out its meaning, or some kind of sorcery is involved here. Baldur's Gate: The Original Saga showed up in the updated list for the third time now.

Starts to smell like a Dragonsphere...

Thanks for posting about the Pathologic update. Didn't get a flag...

Probably because the game's ID in the library is different from that in the catalogue.

Oops, I thought this changelog was for X3: Terran War Pack only.

It was for X3: Terran War Pack only. But that is the game you quoted (here). Did you mean to quote X3: Reunion?

Another one?? Is there a way to get the full list of these titles using MaGog?
Sorry if you've posted about it before and I've missed it.

Oh, I actually quoted the wrong game…
You’re right, I was writing about X3: Reunion.

Posted the Pathologic Classic HD Changelog in the game forum.

No, you can't get it on MaGog, but here is the list (excluding of course the many unbundled games):
- an elder scrolls legend battlespire
- broken sword 5 the serpents curse
- fallout (the new one)
- fallout 2 (the new one)
- fallout tactics (the new one)
- frozen synapse
- pathologic classic hd
- pillars of eternity
- quake ii quad damage
- quake iii gold
- quake the offering
- randals monday
- return to castle wolfenstein
- the elder scrolls adventures redguard
- the elder scrolls iii morrowind goty edition
- the ultimate doom
- the witcher 3 wild hunt

Sorry for the lowercase format. Copied straight from MaGog code.

P.S. And before someone says that I forgot Wasteland 2 --- Wasteland 2 is an unbundled game.

Cheers for the list, but do you mean Wasteland 2 is an unbundled game?

That's what I wrote, didn't I?
