I want to say I was 7/8 at the time. I didn't have any arcades or computers when I was a kid, so all of my gaming was done on consoles, and I was always enamored with fighting games. On my old SNES, I sunk countless hours into MK1, MK2, MK3, SF2 Turbo, and even begged my cousin to borrow Killer Instinct. On my PS1, Tekken 3 was a constant and Bloody Roar 2 may as well have been glued into the system. To say nothing of other odd fighters I'd get later.
Then, one day, my dad brought home a copy of Soul Blade.
The music, the character design, the presentation, the Edge Master mode, THE FUCKING INTRO. It was unlike anything I'd seen before and quickly became a favorite. Li-Long and his Moonlit Shadows theme in Khan Supper Session (which I'm still mad never gets in layer games) are things that associate heavily with SoulCalibur, even if the games themselves don't. Soul Blade is jank as all hell and the combat is slow and archaic, but goddamn the music and visuals are still stunning for a PS1 game.
My history with SoulCalibur as a series is a little funny since I played the games way out of order (SB, 2, 4, 1,5, BD, 3, 6). I unfortunately(?) never played Lost Swords because I didn't have a PS3 at the time. I haven't heard a lot of good things about it, but it something that interest me.
