Why's that ? I had LOADS of them for my XL and later XE.
Star Raiders was and is still brilliant. It was released in the same year as Space Invaders....go figure....
About the 2600: compared to all the Pong clones that everybody had before the 2600, it was a dream machine !
I remember it came with Comat (=Tank) and that was actually a lot of fun to play with my brother. The best game on it was Demon Attack, I still remember I went to buy it with my dad.
149 Dutch guilders it cost, a fortune in those days ! (to compare, the 2600 itself had cost us 499 Dutch guilders, that was after the very first price cut.)
I rented most carts because they were so insanely expensive AND most games were simply not worth buying....
I even remember a friend owned a PCB to run EPROMs in the 2600, ha piracy is as old as computers I guess. I think it was the first time I saw EPROMs and couldn't understand how it was possible to program those things yourself....
However, even an empty EPROM was very expensive for us then
