I miss Bedroom, even though it always felt dated in it's textures.
And then there was one whose name I can't recall. I think it released twice with a different name, the later release I think being a recreation of it.
Anyway, it was some green hills (It may even have been called Greenhills), and two flat areas (one higher than the other), with a deep dive into a small lake.
I built a few projects with friends on that.
But for the most part, I did stick to Slate/Plate2 maps, since I often had difficulty finding a map that's environment would perfectly match what I was building.
And while I was never good at terrain, nor am, and never built any, it seemed better just to have a nice skybox and ground as inspiration, than an environment I wouldn't use.
