The complete Atari 2600 library is something like 17 MB. The Atari Classics Collection only takes up about 92 MB on the UMD, as I understand, so there is by no means a shortage of space. Of course, there was some degree of deliberate selection in what 2600 games were included.
I'm just pissed I can't play freaking 2600 Gravitar until I've bungled my way through the lengthy gauntlet of arbitrary challenges.
