PC normal edition, I don't subscribe to PS+ (for now). I'm not going to until I actually want free games (swamped already) and a PS4 game with online that's not on PC is a must for me (maybe SF5, DC vs Capcom, or GT6 - 7).
This is getting out of control. It has become literally impossible to enjoy all the content available for a singular product. For the Arkham games, waiting for the GOTY edition is about the only way to ensure you have everything because the initial release will spread all costumes and DLC across 20 different retailers and platforms.
