Bearing in mind the recent cease and desist notice from EA to Ultima IV remakes
around the web, I thought it might be good to have a thread to recommend any free-to-play games you've been impressed with lately. These games are often original and intriguing. Also, for those of us with less time for gaming, this may be the best way to enjoy games we actually have a chance of finishing!
I'll start with two I've already posted, which can be played though in a few minutes and are interesting and entertaining:
One Chance to Save the World
and (this one may take longer):
The Infinite Ocean
