I played all of them at the arcades but mk4 I had played the lest at the arcade

MK1 some whenever at the pizza parlor that had the MK1 machine.

I played MK2 once at the movie theatre, but it was hacked so first person I fought was Smoke and I couldn't beat him in the like 5 times I tried.

All in all I've hardly played MK arcade version's with the arcade case. (I got roms on PC and thnx to the latest MK's got MK1, MK2, and soon to have UMK3 on PS2.)
