Classic Map Ideas

Hi everyone, I am currently making a classic-style game, and I need map theme ideas.

It’s a bit hard to explain, but the map will just be surrounding the game area (where I’ve highlighted in red).

I don’t know can u give us a theme for your game? what’s it about? what’s the genre?

What time period you reffreing to by “classic”? I recomand Crossroads, Glass House, Rocket Arena
