I went to Costco today for lunch with some friends. While walking around looking for free food samples, we came across a $2000 machine that has hundreds of classic video games. I found an old favorite in the list, Qix. I used to play a lot of Qix. Like all great games of the eighties, it's simple in concept but brilliantly executed. It's available in all the usual places (like MAME) if you want to play. I also found a fun Java-based modern adaptation, XiQ.
