I don't know if this is a remake and re-modle of the PS3 indie game bought on the PS network, but it is so close to the game Eden that it's hard not to think that.

If it is, I wish some of the original stuff is added into it. And if not, I still wish some of the original stuff was added in. But if you have ever played Eden you will notice how similar these two games are. Same concept, pretty much the same game play. I personally like Eden a bit more. If someone else can do a little research on the link between Eden and UnderGarden that would be nice.
On an end point, I don't know if I should be happy or upset that these games are so similar.
