Free, but commercial
Sometimes Lifehacker is just overwhelming, posting zillions of things per day. Way too many to keep up, and for some reason Lifehacker Australia posts things that it calls “US-centric” which are, in fact, useless to anybody outside the US. Not sure why they bother.
That said, they also post some real gems.
A beauty the other day: a link to the Wikipedia List of commercial games released as freeware.
Some of them are oldies. Some are pretty new. Some of the classics that caught my eye included a 90s era Lode Runner sequel, the classic Sim City, an old instalment of The Elder Scrolls, and that ol’ favourite Elite.
