Mentalepsy: Thank you!
Working from this template, I made a cover for EWJ (attached)... it's a bit amateurish, since I don't know GIMP very well, but I guess it works.
chautemoc: That's actually quite good -- would change the font though, personally. Cover is not the one here, as well, but it's all preference I guess. :)
Unfortunately, it was the only decent cover I could find (I could try messing with the GOG wallpaper to get the logo on there, but I'm not that talented).
Also, every font I tried in GIMP looked like crap at such a small size... if anyone knows what to do about that, I'd like to know.
Here's one for Rise of the Triad... I think it came out a little better than the last one. I'd like to get ahold of a higher-resolution cover image, though, it's a little blurry. (edit: see improved version below)
You may notice I didn't bother with the system requirements or patch line, and I took the blurb from the manual rather than GOG's game card. This is just my preference (though I might go ahead and put the patch version on there for reference after all).
If it's helpful to anyone, here's the GIMP template I put together based on Chaosprower's blank image. Maybe it will save someone some time, or maybe somebody who's better at this than I am can use it to create a better template. (edit: see improved version below)
I didn't know how to make vertical editable text for the spine, since rotating a text field seems to turn it into a generic object, but there are guidelines there that will snap it into place.
((I guess adding a post right after your old one automatically appends it to the previous post. I wonder what the time cutoff is for that.))
