I missed Tales of Monkey Island, I kind of disliked the game aesthetics, so I was undecided about getting it to complete the collection. But, now that is gone, I want it! Lol. The funny part is that GOG gave the game away for free and I missed it for not having it on my wishlist.

I would have liked to get The Walking Dead games too, they wouldn't run on my computer, so it was something I was looking forward to be able to play some day.

I may have been interested in trying other Telltale Games titles, like the Sam and Max and Back to the future games, but I don't mind having missed those.

XIII
Cryostasis

Possibly ARMA but not sure if I would have liked them.

I might have liked some of the Telltale games but as I have never played any, I am unsure.

ADD: The Long Dark if it ever reaches a playable state here.

The only game I regret not buying, I believe it was just the 2005 game not the entire series. I ended up buying the entire series on disc a few years ago.

I own the ones I would really care about as far as I know. XIII, Cryostasis, Duke Nukem. I mostly only play RPG, FPS and point and click adventure games. I have the Telltale stuff I want from their site, DRM free.

Second Sight might be the only one I would have bought if I thought about it. Not sure if I even would have played it though, seems like more of a console style third-person adventure than something I'd be really into.

You must be frothing over the pending remaster later this year then, right?

Armello and Republique.

The Long Dark.

Telltale's Guardians of the Galaxy and République (that I can recall).

Severance: Blade of Darkness

It left before I became a regular here. That and XIII. Both of those are games I wish I had the chance to really get.

Duke Nukem Megaton Edition

They're still on Steam, so they're not abandonware. The new owners just wanted them off GOG I guess.

I have missed a lot of games on GOG which I would like to return, starting from TOCA Race Driver 3, Colin McRae Rally 2005 and Cryostasis, which already had been removed before I joined, up to Back To The Future, where I only realized lately that it has been removed.

Colin McRae
Chessmaster 8000
Second Sight
Severance Blade of Darkness
Dark Matter
XIII
Scratches
Arma series
TOCA Race Driver 3
ObsCure
Republique: The Revolution
Death Gate
The Long Dark
Operation Flashpoint
Armello

As far I know, there might be more :D. The one that I would've liked most is Chessmaster, I think and maybe Colin McRae, but those were gone before I even joined.

That was never here afaik.

Besides many titles already mentioned, TrickStyle and Re-Volt.
