Have a game(s) that even though it's gone on sale -- and sat in your wishlist for awhile -- you've been unable (or unwilling) to bring yourself to actually buy it?

Jazz Jackrabbit and many more other games.

Most everything on my wishlist... generally I use it for games I may want to get at a discount, but very few discounts are deep enough for them. I generally get the games I really want.

Kerbal Space Program.

The Steam version is basically spyware, and the GOG-version is more or less twice as expensive as the Steam version so no alternative appeals to me. I'm waiting for the price to drop on GOG so that it's more in line with other stores, minus the local pricing of course.

Pillars of Eternity is also one of those games I intend to buy and have on my wishlist, but there are so many hundreds of hours of RPGs to play before PoE so it will be many, many years before I'll even consider buying PoE.

Frostpunk- It's been on sale a dozen times since it wishlisted it the moment it got here but i just haven't gotten to it yet.

Parkitect-Same as above.

Shantae Half Genie Hero- The biggest reason is i already have all the previous Shantae games, Shovel Knights, Hollow Knight, The Messenger, Bloodstained Ritual of the Night, etc and are busy with other games before.

Any game with regional prices above base, so all but a few added to GOG in the past few years and plenty of earlier additions too, since I won't purchase those or cause them to be purchased on request (such as a trade or giveaway where I'm free to ask instead of picking from codes already purchased). Also any game that didn't go below $6, since 5.99 is most I spent on one.
But those that have been there since before the "good news", and even since before GOG started adding pricier games, are the Ultimas and Zeus. The Ultimas were added out of a more of a historical interest, a long-running classic series, was that and Might and Magic, and my first GOG purchase was the Might and Magic series, Ultima was left aside and that's where it'll probably remain, doubt I'll bother with it and considering how I set aside M&M1 and decided against trying 2, and haven't gotten around to the rest (not counting 6 which I had already played and finished before, and 7 which I had played and abandoned after that). As for Zeus, had more of an interest in that kind of city builders then, doubted it more and more since, but either way may be left even more as a single token game I hope won't have regional price hikes and I may actually purchase someday, if I'll ever run out of things to play and all the non-classics in the catalog will be that way someday. Seeing as, at the rate I play games, I have enough for the next decade or so, highly doubtful, but just in case.

The Witcher 3, as far as my wishlist here is concerned. Every time it goes on sale I either don't have the money to buy it or just completely forget it went on sale and buy other stuff that's on sale only to eventually go "dammit, I forgot to buy it again!"

One of these days it'll be when I have the money and not the memory of a goldfish.

Yeah, Pillars of Eternity sat on my wishlist forever... and still does. I got a free copy (with DRM) through Twitch that I planned to play and see whether to spend teh money on a GOG copy, but haven't even loaded it up. Something is keeping me from buying and playing this game!

I've also waited forver to buy the Alan Wake games. Thought the short delisting of American Nightmare would get me to buy the base game ASAP... but no.

Same here, even though I can't even run it on my current setup.
It's just so cheap on sale, and I'll most likely get around to playing it even if it's years down the line.

American Nightmare wasn't delisted, it was the first/base game that was.

Freespace 2

Everyone says it's one of the most iconic PC games of all time, but I can't pull the trigger on it for some reason.

Understood, but the issue was when it was delisted I went on Ebay to find a physical copy and didn't buy it. When it all came back to GOG I just forgot about it.

IMO Alan Wake is good at any price around 10-20 bucks(full game with expansion)....to me it's THAT GOOD.

Thanks.

Yeah, I keep hearing that. I'll definitely be trying to pick it up sooner-than-later.
