Perusing the wishlist on GOG.com is an entertainment in itself.
I spent a couple of hours already reading through the titles, reminiscing on the fun moments I had with those I do remember and looking up in the net those, which I do not.
I have also added a couple of those which evaded the deserved inclusion up to my interference and intend to continue to do so when I stumble upon new ones.
Right now I have a problem, which I hope you can help me with.
I really want to check if one game is on the wishlist, it deserves every vote it can get, but I can not do so. It does not even start a search.
I suppose, that the problem is the coded limitation of the search engine: the game title consists of one letter.
So could someone clarify, if it is even possible to enter a one-letter game into the wishlist and how it should be done?
And in case it can not, the solution point will go to the one who guesses the game, so that your attention is not wasted. (and I know it is easy, and I really would prefer to be wrong about the limitations)
Thank you in advance!

Is the game Z??

I told you it was easy :)
Now that you have guessed the title, all you have to do is prevent all the others from answering my main question :)

Done and done. Makes me wonder, how did the guy who put it up there manage to enter the single letter without the colon. Do you mind answering this one too?

Maybe he put a space in...a space still counts as a character in most systems/places...

I know of 2 one-letter games: Z and D, both will be found if you enter a number after the name (Z2, or D2, for example). However there's also one labeled "Z: Zed", which I assume is the same game as "Z", that one can be found by a number of searches:
"zd" gives you "Z: Zed"
"zed" gives you "Z: Zed" and two unrelated games (that has "zed" somwhere in the title)
"ze" currently gives you 50 games, among them anything with "zero", "panzers", "dozen"... and both "Z" and "Z: Zed"
Yes, one-letter titles are a bitch, I'd say the most solid way of finding them is to add a digit, though you won't find alternates (like "Z: Zed"), there shouldn't be too many such titles though.
I believe you can ADD a one-letter title, but not SEARCH for one (because you'd find every title containing that letter, which would be a lot).

Well the number should not exceed 40 or so, unless the titles are in traditional hieroglyphics, but then everything gets complicated in hieroglyphics, not only the game titles. :)
