Allow me to start this with a preamble: I love GoG and what it has achieved in regards to bringing old and indie games into the present day. In addition, until today, their pricing so far has been almsot universally fair and balanced.

So what happened here?

Why does an 11 year old game without any multiplayer functionality cost 40 bucks? Is there something I'm missing here, or is the pricing waay off for an archive title?

That'd be a question for SEGA since they're the ones setting the price, not GoG.
It's still 75% off or are those 8,79 eurodollars still too much?

imo its worth the $12 i payed for it but no one has to buy it if they don't want to

Yeah, the discount price is perfectly reasonable. It's the full price I don't get. I'm not exactly trying to stick it to the man and scream at the corporate heavens, I'm asking how this will be in any way a valid purchase prospect once it goes off of sale!

I am looking at the Galaxy version, and I don't see any option for multiplayer nor any DLC.

:( Preview variant of store page directly say it be An-ry edition and include all DLCs (they been listed next in desription). I hope they remove it only cause of offline version (better to be Galaxy users surprise bonus content instead of advertising features not included for offline-only buyers).
Well, anyway anything better than always broken steam-builds and steam client itself. Most of DLCs content are for MP reskins, its still good DRM-free offline game and normal offline installer game version. Im personaly not looking for mp and DLCs, but why Galaxy client exist if it provide same offline-only half-games...

In the release news announce thread there is discussion about it. God point for local coop. Im personally more interest in DoW, and DoW Steam version after merging to Steamworks is downgraded. RomeTW got LAN possible restored. DoW is not.
Supreme Commander 2 on GOG got MP removed, but GOG galaxy build use galaxy.dll for no reason (do nothing). MP is almost there, but they still remove it. Maybe some licensing agreements issue betwean publishers and GOG for their onlince services.

Some games got multiplayer (+LAN) removed even with skirmish mode.

Have nothing (literally removed button in menu) of original multiplayer is big disadvanatages. Why there is no LAN? And looks like this is coming from GOG for many games here (similat way for each - removed button not matter if there is originally LAN\skirmish).
So it is another lie from GOG (like compatibility issues for Army men games or licensing "issue" music for Quake 1)

Anyway better to have it here at least in some way to play, if it still be offline DRM-free game version. At least it have singleplayer.

As for Dawn of War, if GOG got same or more disadvantaged version as Steam... im keep using disc versions (there is un-official MP services for DoW1 games working as Virtual LAN).
Steam anyway worse way to play any games, including online.
