Minecraft looks like stuff.
Was it easy in anyway what-so-ever? how long did it take you and such?
You have to be willing to learn. It's quick to get started, but it takes a while before you can make anything decent.You'll need Valve Hammer Editor 3, which is for the Half-Life 1 engine. You will also need the .fgd for Sven-Coop.http://scmapdb.com/mapping:setup/
