Yes, actually stood in line 9/9/99 official US release date to purchase it, it came with a large t-shirt with the logo on it. Still have my original system from back then today, although the laser is weaker.
What made me interested in the system and wanting to buy one was the fact I was a regular at the arcade venue where I live. I remember playing games such as Power Stone, Street Fighter 3, and Marvel vs Capcom being in awe how awesome these three fighters were. A few weeks before the launch also played demos of Sonic Adventure, Marvel vs Capcom at Toy's R Us retail store.
This was really the next-generation system having the specs and graphics to push all the boundaries at the time for a home-console. I became a SEGA fan (from being a NINTENDO fan owning a NES, GB, SNES) since owning a SAT first, playing AM2 arcade classics, and reading video-game magazines upon the upcoming 128-bit powerhouse.
Sega Dreamcast is one of my top five favorite consoles of all-time, with a strong library of arcade ports that converted smoothly thanks to Naomi board. Other arcade games I've played were; Spawn in the demon's hand, Tech Romancer, Soulcalibur, Dead or Alive 2, The House of the Dead 2 that were to come home on the system.
Years later when PS2 was released my friend gave me all of his controllers, VMUs, and a few games. I would discover the Japanese imported games that were never released here and would enjoy the system even more.
