We could use a extra backgrounds to appear *behind* the sprites as well.
Agreed. As long as the quality is good.
Yeah, the current one isn't good. It's a photograph of the view from the window of the apartment I lived in when I started on GH1-SDL.
Actually, I kind of like it. I think it's usable. However, the bright colors might be too much of a color contrast - making the black outline of the cartoon portraits stand out and seem more pixelated.
Here are some alternate backdrops I made a long time ago.
They might be too realistic too.
The backgrounds are just backdrops and, as such, seem barely noticed most of the time. At least, I don't usually pay them much attention.
I don't recall it being stated that the background had to fit the 1980s cartoons look. Besides, IMO, neither of yours contrast as much as the current backdrop. The first one is especially fitting, since the color palette seems dark and a bit 'toon-ish.
Here's an idea: How about a script where the portrait background
changes depending on the terrain? If implemented, I know I'd pay more attention to them. Some examples:
* Lunar City - Urban background with tall buildings, with dome and lunar surface visible
* Lunar Outpost - Suburban - some buildings and facilities, dome and lunar surface visible
* Lunar Surface - Barren rocks and craters
* Asteroid Outpost - Like Lunar Outpost, but the surface is rock of a different color
* Cities and Ports - Background appears very urban, with tall buildings
* Towns - Background appears suburban
* Village - Background appears rural, with few houses or buildings
* Wilderness - Background appears lush and green, with lots of trees and a stream
* Spinner Town/Port - Background appears urban, but with cylinder of Spinner wall visible
* Spinner Park - Background appears lush and green, with trees and streams (and wall)
* Spinner Farm - Background appears green, with fields and/or hydroponics (and wall)
But then, many characters nearly fill the portrait area as it is, so the background is not normally very visible. So such efforts might be for little return (unless the backgrounds were made bigger than the portrait).
