This is definitely the definitive edition of this game with all of its great additions such as Tails and including both the JP and US soundtracks; however, as some fan feedback, I would appreciate if this (along with the great iOS remakes for Sonic 1 and 2) was ported to PC for Steam, PS4s PSN, or Xbox One. I know that SEGA would have to be the one to greenlight such a project, but it would please people like me who typically dont play Sonic (but are attempting to get into the series with these iOS/PS3 remakes). Also, Sonic 3 & Knuckles on iOS could work as well as the previous installments remakes. SEGA is sitting upon many obvious gold mines in many ways right now, but they seem to refuse to even try to dig it up, instead being in favor in releasing/publishing games that are either unfinished (Sonic Boom) or rushed to meet a deadline (Sonic Lost World). I know that Taxman & Stealth has already demoed a concept Sonic 3 & Knuckles iOS port (although not greenlit by SEGA), and I will be surprised if it hasnt began development yet, considering that this is yet another anniversary for the series this year.
