OG XB. Mostly due to nostalgia. I was of the mindset that bigger was always better at that age, so the XB console seemed amazing to me. Plenty of good games as well. The graphics blew me away vs PS2. Was a relatively big Halo fan at the time, but had halo for PC though. Never got an XB because our parents got us a PS2 eventually. Just convinced them to rent the XB from Blockbuster a bunch of times. Ended up wanting and getting a PS3 instead of 360 because of the power and potential, plus the bigger size. OG PS3 was mesmerizing. My brother got a 360.
Loved the Duke the most. Was just old enough and had big enough hands that it fit like a glove. GameCube controller was a super close 2nd.
