Hooray! One of our favorite "brain games" has made a triumphant return to Windows Phone 7: Brain Evolution 2 by SPB software. SPB said Windows Phone 7 was an option just a few weeks ago. Guess they weren't kiddin'.
It just went live in the Marketplace and fetches for $4.99, which is on the high end for a non-Xbox LIVE game these days. Still, we've always really liked this game so we're gonna give it a thorough trial.
Thanks, @paulwillen, for the tip!
