Thanks to Dynamithix, I picked up Child of Eden since it is a prequel to Rez which is one of my all time favourite games, so I saw it on offer for £25 brand new at Game, I took it to the cashier who told me that they had a pre owned copy for £19, so I went for that, but turns out that they were sold out of pre owned copies so I went for the new one instead, but the guy still only charged me £19
When I got it home I was a little dissapointed, at first I felt that the game was bizarely confusing and just felt inferior to Rez, but when I played it more and more, I am now of the opinion that it is better than Rez and it is now one of my all time favourites. Totally love it, but it can make you dizzy if you play it too long...
