I never really got into the first one but the second was definitely on my radar. Probably because I was actually able to play it in arcades before it came home. The first one was so packed in arcades that my first real experience with it was renting it on the SNES, not exactly the best option but it was the only one I had at the time.

I tried playing MK3 but could not get into it in arcades so I just stuck with the second.
