This was the first conventional, popular game that my parents ever bought my family for our old Commodore 64, and as a result, I played it ravenously. Now, ever since the advent of emulators, I have been playing the MAME version of it quite voraciously. I like pattern games. I like them a lot. I like them because they have a purity and a simplicity that is completely missing in 99% of the games that come out for computer systems today.
