Game Editor is a very powerful tool. It can allow a beginner to make simple games with limited knowledge, but also allows a person with advanced knowledge to make advanced games.
Here are some screenshots of my upcoming game, tentatively titled 'nova epic'. It is a full fledged space rts, featuring everything you'd expect such a game to have, battles, attack behaviour, tech tree...and sound clips for units, with extra 'funny clips' when you click too much, like starcraft. Hopefully beta testing can begin at the beginning of february.
