The first game I ever beat in my life was the NES version of Teenage Mutant Ninja Turtles: The Arcade Game. I was so happy when they announced that they were including this game in this collection. Not all of these are what I would describe as "winners" per se. There were three titles: TMNT NES, TMNT II Game Boy, and Tournmaent Fighters Genesis that could be best described as an exercise in patience in finishing them, EVEN WITH REWIND. However, I loved my time with the other titles, especially The arcade version of Turtles in Time.

I haven't even played online in any of these games yet but yet they offer an online mode for The Arcade games and the SNES version of Turtles in TIme which I think is really nice feature I hope to try with my mates sometime.

I guess the one advantage of this versus downloading it directly from the retroarch website is Steam features like time tracking, visible screenshot sharing, etc. You can import other retroarch cores not included in the Steam version too. Its a hell of a collection of emulators and since I own every game ever( just stored in a storage shed in Switzerland), it makes it super convenient to play what I assure you are my "very legal backups."
