So I figured I'd take my own advice and try to work out a map layout by picking a pattern and going from there. Here's the basic pattern I grabbed, with color-coded areas. Orange being rock, red and blue being buildings appropriately themed, grey being ground. I'm thinking the spawn areas would be off-map, relative to the play area, stuck at the top and bottom. It's laid out more or less in a 13x13 grid, which can be scaled up and down as needed (I'm thinking each square would be 256x256, putting the playable area at roughly 3328 units in diameter, or 8.32 seconds across for a Scout, 41.6 seconds across for a Heavy with the minigun spinning) and probably about three squares high. I haven't given it any more thought than this, save considering some hard ceilings in areas, and figuring I could run various paths through the rock and buildings. Here's what I'm looking for input about: What sort of game type do you think this would work best for? Do you think the map's flow is good? Do you think this would be a royal pain in the butt to map? Would you suggest any changes or tweaks to the layout? And of course, any flashes of inspiration are welcome.
