Aquaria is already here. :P

*facepalm*
My bad...

No.

Don't Be Cruel

ok :'(

If it is, I think we'll all need to re-evaluate both how we interpret these hints as well as the level of sanity the gog blues are operating at.

Aqua - Barbie Girl huh? ... That must be the first time that I'am thankful that the GEMA don't let me watch some music videos! :)

My guess is an JRPG

Oh I forgot to guess, ehh don't know if there's any Plastic Surgery Simulation out there, but if yes then it will definitely come to GOG ^^

"Plastic Surgery Tycoon! - Increase the T's and P's! Decrease the brains!"

Fun! :D

A few more guesses:

Subnautica
HunieCam Studio
Tomb Raider
Lego Pirates of the Caribbean
Five Nights at Freddy's

You know that the game is already here. Unless you mean 2013 version.

Anyway, posting list of games as a 'guess' isn't a smart move - someone can post half of MobyGames to increase his chance.

I would guess the next two Neptunia games since we have the first here already.

*edit to include Fairy Fencer F since sequal is out today.

hmm, no Aqua -> Dune ?

Yes, I mean the new Tomb Raider. And my guesses are no arbitrary shots in the dark. I took half an hour to compile that list based on the hint, trying to avoid games that have already been mentioned. Edit: I'm late to the game, and there have already been many good guesses that I deem my chances very low. Naming more than just one possible game might indeed increase my chance in case no one has hit the mark yet.

Hmmmm... Japanese subtitles, barbie girls you can undress...

Akiba's Trip: Undead & Undressed
or
Senran Kagura Shinovi Versus

I'd say Shinovi Versus. It was supposed to come here but hit technical difficulties. Maybe they found a possible way around them hence the uncertainty.
