Our family got a 2600 when I was probably like 9. I HATED those sticks with a passion.
Id already been introduced to far superior controllers on the c64, as well as the Arcade machines.
The Stick was an nightmare.
The shafts hard angles cut into your hands, and felt horrible.
The plastic covering wasnt flush with the internal shaft.. and add that to its ridge rings that were too close together, cause it to make loud noises, similar to that of sitting down on a leather couch.
The stick had pretty much Zero travel. The stick assembly was made to be pressure-bent. Wretched design.
The button placement, and its small square base, made it impossible to use on a level / floor surface. You had to play it in your hands.. and so had to deal with bulky non-ergonomic block in your hands.. with poor shaft leverage, and use your worst / slowest digit (thumb), to press fire.
The problem with childhood memories, is that they are always foggy and colored with childhood ignorance / poor awareness.. and rose tinted glasses. Pick up a real atari stick today, and compare it to a happs comp. Or in fact, just about Any stick based controller. Its hard to find one worse.
The only thing I can think that Might have made the stick less of an issue for some people.. may have been a hotter climate. Its possible that hotter climates caused the plastic to be much more flexible, and thus much more forgiving and possibly even more comfortable.
