Base on the previews, I can't decide which one I like better, edeN or Vault That Borderline. The other one was just meh (expected it to be lolish).
Also AmiAmi has all 3 games in one package:

Apparently their exclusive will give you access to a clear save for all three games which is stupid since that just ruins the fun. At least you get a bag for it.
