According to this site, The Game Factory will be developing a new Garfield game that is set to release next month. Garfield already has 12 titles.
The site also mentions that a Garfield movie sequel is to be released later this summer. I’ve been able to confirm that on Wikipedia. while looking for information on this upcoming movie, I found an estimate that the first movie generated $245 million (domestic, international, video sales combined). That number surprised me as I thought the movie had pretty much bombed – but I guess not.
