osm: Isn't it supposed to be uncropped non-CGI shots?
Lone_Scout: No, it isn't. As long as it's a screenshot from the game. Cropping the image or editing it a little bit so that it is not so easily recognisable (or at least googleable) is not such an unusual practice.
There's the problem - how big the little bit can go up to? Why not just post a single pixel then?
Here's where *I'm* coming from - it has to be fun both to post a riddle and to guess. If we allow doctoring the image (why only crop? why not change the palette or black out half an image in a checkered pattern?), it TAKES OUT THE FUN of
POSTING the image. For example, on my previous post the game I was going to post turned out to be too recognizable straight away for google, presumably due to a distinctive UI, which is unhidable by normal means. So what did I do? I've turned to another game altogether. But I could've easily just crop out the sidebar which was giving it all away. It's not the q of harder vs easier it's about to having fun to find a screenshot that is both "natural" AND hard to guess.
