Random Generation of the Island to improve replayability.
Random Map Generation
Random generated map as says. And random generated resources place and depths on those maps.
It would get a greater "reward" feeling if you solve the logistiks problems on a map " you never seen before".
As for today to solve problems i have found myself restarting on same island over and over again when i have "built my self in a corner" rather than trying to solve it. "(i can do it better)"
It appears that there is a different code generated every time I start a new game on the same map, But I see little difference between the placement of stuff on my Island maps compared to other pictures on the Forums and on the Youtube videos. ( Except maybe for pictures of the game on earlier versions before the Early Beta release on Steam.)
Not sure how long it takes you to add a standard map, but more maps in general with item placement randomized as a game option would make a game start more appealing. Yes, it is easy enough to keep failing on the maps included for one reason or another, but variety is the spice that could make a great game even better.
It would be nice to have the ability to randomly generate some things, like a River system. I don't think the new Map Editor can do that yet.
