Personally, it still feels way better. It might just be a massive case of preference or something. Even if it was just the ILLUSION of better gameplay, it still feels better than this even now. I'm still waiting for AA3, and ALL they would have to do with that for me is just make it full 3D like Koikatsu (or even this, AI Shoujo), and that much ALONE would be the best possible upgrade for me. I could download it TONIGHT and still find insane amounts of joy in it compared to this right now.
(Extra additions would be giving the "outside" school life feel more alive as well in some ways of some sort.)
The best experience right now in the present day would be getting AA2Mini, and actually utilizing the modules function, creating/making or downloading them, and attaching them to the characters, enhancing the gameplay in a way that the base vanilla game doesn't already allow for. (Or hell, even make scenes using the AAUnlimited's posing functions.)
(Of course, at the end of the day, all THIS personally is just me, but I'm sure there's still people that would agree, even if only selectively about some parts.)
