Ha, man, I thought i was gonna be the first person to mention the TI. Jungle Hunt was the coolest, never thought swinging from vines could be so tough. Also remember Parsec, Alpiner, and TI Invaders (think Asteroids, mountain climbing dodging boulders and snakes, and Space Invaders).
Then sometime shortly after, the NES magically appeared one Christmas and I still whooped my dad even though he hooked it up and started playing Mario the night before.
