I originally found Fish Tycoon on MSN Games. I liked the trial so I bought it. When I finished the game, I couldn't figure out how to restart, so I went searching for reviews, and ended up at Shockwave.com. Amid all the yakking - there's three pages of reviews! - I found a reference to the creators' home website, www.ldw.com. And, ah, here I am.
