Softball, I forgot about Majestic! I beta'd that one too.
At the time it seemed so real and was pretty freaky...X-Files type stuff.
I think it went online for maybe a month after beta and then was cancelled by EA...go figure...when the Sims Online was about to come out.
Hitachi, I tried to get in on the AAO beta early on, but guess I didn't make the cut. Maybe because I was just starting to test SFP1 at the time.
