I would honestly recommend honey select 2, especially for a higher chance of getting new people to play mnf2. Honey select 1 does already feel a bit dated, and if you plan to update mnf2 as long as you did the first, the difference to other, newer games would be potentially quite big. I would also think that a lot of people who currently dislike the look of horny select 2 would Stil get used to it fairly quickly. Although ultimately it's of course your choice as you know more about the game and your community. I will definitely play it either way.
