Refunded my Steam Pre-Order (my Collector's Ed was a Steam code anyway) and just Pre-ordered on PS4. Funny my Sonic 1 Rom is not listed in my Mega Drive & Genesis Classics list anymore, but it's still listed in the simple launcher.
Adding to why people would want the Taxman versions of Sonic 1 and 2, the audio! Main Gawt, the audio is pretty bad with the emulator they have in the Steam Shell. With Taxman's version you get the accurate and even remastered OSTs. Hope it happens one day!
