basically im looking into getting together a small collection of (gasp) FUN games!, not so much interested in rarity, but quality from atari age.

i never had any of these consoles so im obliviouse as to which one was king. of course i have to assume it was the atari 2600, but you guys have to know better than me.

basically i mean late 70s and the pre-nes 80s. which console was the clear winner when it came to FUN and pretty (HA) games to play? intellivison? collecovision? 2600? others?

what are the pros and cons of each, and ultimately, which bring more pleasure playing (i have no nostalgia with the era, so please, gameplay is all thats important).
