Azada! January 2008.
It started because I was in an adventure game rut and just wanted straight puzzles. I was playing Safecracker and I saw someone on another board suggest Azada for someone looking for just puzzles. Did a google search, found BFG, bought it and signed up for a 12 month membership.
I'm addicted to casual games now as much as I have always been with adventure games. In the past 2 months I have purchased 20+ games from BFG. Help!
