I decided to have a quick peek at the maps for Worms United. Some discoveries:
MOUNTAINS
They all have mountain sets! I had entirely forgotten that. Unfortunately, Worms Utd's mountain dimensions are entirely different from WormsDC's, which I already kind of knew from converting the mountains for the MONEY terrain, but yikes! I have to choose between drastically changing how the mountains work for WormsDC, or just abandoning them entirely... but the fact that the few maps from Utd that Team17 converted themselves for DC included a mountain set means I'd want to go after that uniformity. So the Worms Utd stuff is definitely going to take longer than everything else. Yikes!
DIMENSIONS
A standard Amiga Worms/WormsDC map is 960x350px. This is 50px shorter than the maps in Worms Utd. For the most part, I don't think this presents a problem - there's usually enough space at the top or bottom that cropping isn't an issue. There are a couple of maps, however, where this isn't going to be possible, so I have to make some hard choices. That Windows 95 map, for example! I would probably have to lose some of the icons at the top of the map, and if I do that is it still the same map? Again, this is something that's going to require a lot more work than the WA maps, which after resizing are actually only 2px shorter than the WormsDC mapsize.
