I am not a fan sadly of RPGMaker... I did forget that in my pole though.
Nostalgia... or able to give you different change between game and animations.
I think an HD2D game would be very interesting. I like another chance and I thought they created their own engine but I guess was a different game that made their own.
I strongly dislike the paywall for CORE game content if most of the game is already free. As for additional add-ons like different fetishes I can see it though.
