I haven't thought about this in a while, but some of my favorites off the top of my head:
● Keystone Kapers (is definitely my favorite)
● Chopper Command
● Demon Attack
● Freeway (I thought this game was HILARIOUS in 2 player as a kid)
● Frogger
● Lock 'N Chase
● Missle Command
● Pitfall
● Raiders of the Lost Ark (really)
● River Raid (maybe)
