I own everything I'm interested in.

New tier of Interplay discounts: 19%-off. Very avantgarde!

Just a heads-up, the game "Forgive Me Father," on the list, is still listed at full price though the game's store page is showing the 20% discount.
Edit: Same with Necrovision and it's expansion below it and Dread Templar above it.

Haha, comment of the day! :)

... and it is soon over.

I may or may not get Soldier of Fortune if it's seemingly fixed now, but yeah, it's either games I already own or don't have much interest in.

Though I would ask how SWAT 3 holds up to 4. There's always this anxiety when you go from a very good game back to its predecessor and it's not nearly as polished, any idea if that's the case there?

Mmmm... retro shooters. Amazing moment to make available Chasm The Rift in GOG right now before the Steam date, :D

Serious Sam 2 and 3. Dead Island Def Ed (even if multiplayer is gutted). DNF. pls

You would play Dead Island in SP? I've tried to do that with the beginning and it's very obvious that it isn't the intended way to play it. On top of that everything feels so much worse than Dying Light.

Sure. I did, it's fine, finished the game. I'm not sure I even knew there was any multiplayer.

It's not as good, but when it came out it was decent and Dying Light didn't exist.

I've never tried it but I'd be interested at a nice sale price. though I'm sure I have nostalgia bias watching theRadBrad play it back around 2010.

I can't imagine GOGgers getting the game with multiplayer intact. Techland won't spend the resources to port it for such a very small return on investment. Fair enough if most people will only buy a GOG release if it has Galaxy multiplayer, but I don't care personally.

It's an insult that TRON 2.0 is not on that list! Plus I have it on my cart :'{

Chasm: The Rift is hopefully coming.

I'm still waiting for Z.A.R. to appear here. Come on GOG. Add the mission pack to it too if you're feeling extra spicy.

Klingon Honor Guard would also be nice. As would be completing the Serious Sam series, especially 3 (+ Jewel of The Nile) and 2. Others are not as important.

Also strange that we don't have Medal of Honor: Airborne here, seeing as we have the other old Medal of Honors.

And don't get me started on the original Doom 3 + RoE.

And Aliens vs Predator 2? Anyone?

Still plenty of stuff to add here. Any of the above would be insta-buys.
