Ah, that explains it. I paid 50 just for the system...already pretty hefty

It's aways funny to see that certain games are very rare.
When Atari Benelux died, they sold a big chunk of their inventory to a toy chain store here called Intertoys, who dumped them for low prices. It was mainly 65XE's with 10 cartridges. Those games you see "thousands" of still here because it was apparently a small selection of games they had...
I never played Battlezone on the 8-bit, I think that was a "dedicated" XE release right ?
