If you want, post here your statistics for GOG's Summer Hidden Gems promo (the 18 games promoted over the last 18 days), using the following five-line format.
If enough people post, in a few days I'll publish a summary of the results of this impromptu survey.

< FORMAT START >
Already Owned on GOG: x
Wishlisted & Bought: x
Wishlisted & Not Bought: x
Not Wishlisted & Bought: x
Not Wishlisted & Not Bought: x
< FORMAT END >

If you were given one (or more) of the promoted games as a gift during the promo, COUNT IT AS IF YOU BOUGHT IT (or them).
If you gifted one (or more) of the promoted games to someone else during the promo, DO NOT COUNT IT (or them).
Whether or not you own a game off GOG (Steam, CD, etc.) is not relevant to this survey.

The total should be exactly 18, as there were 18 games in the promo (the survey refers only to the 18 promoted games).

P.S. If you are not sure about some of the numbers (e.g. differentiating between those "wishlisted" and "not wishlisted"), just guesstimate and/or add some explanatory text

To kick things off, here are my statistics:

As you can see, I have little willpower when it comes to deep discount promos. Thanks, GOG, and keep 'em coming.

And one of those bought was actually gifted. I had good self control, yay! One was also already owned from another source.

*edit* received another as a late gift due to an awesome GOGger. :)

The one wishlisted game is Unreal Gold, and I actually wishlisted it a week and a half after the promo, when the Great or Significant Gaming Memories thread made me realize how much I enjoyed it back in the day :-)

None of the other gems were interesting to me. I did, however, buy four games during the staycation sale.

* I am weaning myself of games again. Focusing on other interests that feel more worthwhile, again, lately.
* Am working on my MA dissertation.
* I don't have any money to spare.

The one game wishlisted and not bought is The Longest Journey. With my backlog, I don't really aim at buying $10 games unless they get a good discount and I feel like playing it at the time. I don't feel like playing point 'n clicks right now.

Had a lot from non-GoG sources (i.e. Unreal, Dark Reign, etc) though
