Good news, I'd say! I tried D:TW when I first got my 3ds since I skipped the DS and really enjoyed the gameplay and atmosphere, but could never make it very far due to the crappy save system. Also really enjoyed Moon and the 3ds re-release. Renegade Kid does great games and I'm sure the updated version of the Dementium games will be worth the price.
It'll be awhile before I figure out how to do one of these. :P
