Got Atari 2600 twice (amount of games, not a 5200).

Got some 1st party ones for a change. Air-Sea Battle is a pretty typical early/launch title for gen 2 systems, shoot moving targets with a focus on 2P (it does have some original variations). Midnight Magic is a competent post-crash port but with its own simplified and less interesting table. Night Driver is actually neat in that it is an enhanced port of the old arcade game, adding oncoming cars and some eyecandy. I also got Swordquest - Earthworld, which is just an incomprehensible puzzle masquerading as a terribly bland "game" where you need to stuff objects into rooms (some guarded by minigames) in a specific order to get clues.

The rest is 3rd party. Alien is a cynically licensed but decent Pacman clone. CocoNuts has you dodge Coco's Nuts, LCD game tier design. Dragonfire has you avoid some fireball (horizontally) to then grab treasure and avoid more fireballs (topdownish), plays nice and fast and a good example of simple design. The Earth Dies Screaming is a cockpit shooter where the vertical aim is managed for you, the only other point of interest is having to follow certain enemies to kill an enemy to replenish your/earth's energy. Fire Fly is a simple (in a bad way) shooter with some different enemy types, little in the way of graphics and annoying music.

The last for this post is Piece o' Cake where you need to construct a cake in multiple layers, the cherry signifying a completed cake (even if it's just a plate). It quickly becomes too fast to properly play though, which is a bit of a shame.
