I was just looking around on the PSN store before and found this, a little bit of Googling later and I've found that it's due to a pricing error. Anyway, all 3 PS3 Doodle God games are now free on the AU PSN, not sure how long it will last, so get it while it's hot.
Included are
Doodle Devil
Doodle God
Doodle Kingdom
Unfortunately, these games are not cross buy, so you won't be walking away with the Vita or PS4 versions. Speaking of, they are going for 23 bones right now, so you can imagine this would be the same.
awesome ta!
