I'm interested in the PS3 assets you're bringing over, that was one of my biggest concerns over the announcement of the PC port, that there was a PS3 version with superior graphics and more content. I didn't like the idea of playing an inferior, obsolete version of a game.
I'm very interested in seeing how close to that version this port is and if it ends up being the definitive version of the game you seem to be promising.
Personally, I'd prefer a figure to an artbook, I can see Sonico art easily on a booru, a figure is more unique.
You should just throw both the figure and artbook into the limited edition, or have the figure as part of a deluxe version (only difference being the inclusion of the figure) for those who'd prefer not to have one.
Man I really want to get behind this, I like what im hearing, but considering the state Shiny Days is STILL in, I'm still too salty to get myself invested in this, I don't think the steam release would matter much in the way of censorship considering this game was also released on console i.e there's nothing explicit here afaik, but I'm still weary of potential surprises somewhere down the line outside of censorship.
I will keep a close eye on this project but I have no plans on preordering atm, I hope it turns out much much better than Shiny Days though and if it does release with no issues, I'd consider it.
