One thing that always strikes me is how phenomenal the sound design is. Yes, the music is obviously fantastic, but the BLAST of a charged Mega Buster never fails to impress. Dashing around, climbing up walls... It's just so much fun. While the story is nothing special, there's this quality to the X bootup cutscene that pulls at my imagination. And then the title screen! And the intro stage!! Someone at Capcom knew how to bring the HYPE. Timeless!!!!
