Few people here hatin' on the 2600! What's up with that? Warlords is one of the best 4p games hands down, even to this day. Some other good ones mentioned too: Kaboom, Megamania, Missile Command, Yar's Revenge. Let's not forget Berzerk (a fav of mine), Frogger, Space Invaders, Turmoil, Gyruss. Respect the 2600!
But to answer your question: it's sadly been a while since I've played mine. Getting my refurbished ColecoVision back this week from a member of the AtariAge forums, so I'll be playing that for the forseeable future (and I'm giddy with excitement)!
