mine would have to be vf1 since it came with the machine that i bought way back in `95
i remember paying a deposit for the saturn so i had it the first day it was available here in the uk i also paid alot of money for it as well think it was £299.99 i also got about 5 games that were released on that day as well but vf1 was the first one i put in and played.i sold it for only £80 a few months later due to lack of good games and a certain other machine
popped up and my hole world changed ,but hey i got a saturn
again as i got hold of a chip for like £20 and guess what it also had with it a vcd cartridge so i chipped it and started getting all those lovely games i missed ,and for the other certain machine i dont even have one of those anymore
well not exactly i have its bigger brother,but i do love the saturn for all those shoot em ups that i like ,,
