I was playing my Flashback 2 system this weekend and noticed some games on it were VERY late in the systems lifetime (1989, 1990), and they were far more advanced than the earlier titles...just shy of NES quality...almost. Hell, Yars' Return was 2005.
I got to thinking...what Atari 2600 games are actually beatable...not just games where you try to get a high score or just repeat endlessly.
Here's the ones I could think of off the top of my head:
Adventure
Pitfall!
Pitfall! 2
Indiana Jones: Raiders of the Lost Ark
Swordquest (all of them)
E.T.
Superman (I think)
EDIT: River Raid...once you DO get the highest possible score, the game freezes and the score stays at !!!!!!, so this counts.
Can you think of any others? I think it would be cool to have a list of these.
