In my opinion, I think default map for Sandbox gamemode should not be an island. Here's why I think so: -A lot of vegetation is obstructing player's view. -A lot of bumps and objects in the way (especially not good for vehicles). -A visual cluster. -Generally not a lot of space to roam around. -(Probably) uses more hardware resources than needed. So here's what I'm suggesting: -A map that is visually appealing while being centered on being flat. -A map that offers alternatives for testing various functions, such as water, underwater, hills, sand, snow, ice, high altitude and clouds (even space if possible), etc. -Some structures such as airfields, a few tiny towns, a few asphalt roads, etc. (for testing out, but it's not the most important imo) -Destructibility would be a quite a nice addition too. -A pretty big size map in general, to enjoy high speeds from vehicles such as cars and aircraft. This includes big heights too. -Flat areas should avoid high bumps or not have any bumps at all, in order to enjoy using high speed vehicles better, such as cars and aircraft. ---------- In other words, it's something like Just Cause-ish, but without visual cluster or buildings/infrastructure everywhere (nor humongous size obviously). A pretty decent example would be a map from that unnusucessful sandbox game where there is a big flat desert area surrounded by mountains/hills.
