I previously blogged about two of my favorite digital game collection, but I recently discovered another one.  Big Fish Games is a digital game collection similar to Real Arcade and Pogo.  It has free games online as well as downloadable demos.  The site has a pleasant arrangement and divides the games into different genres (hidden object, puzzle, adventure, etc.) making it easier for users to find just the type of game they are looking for.  Big Fish also offers a game community for users to play games with or against other users.  Big Fish also offers games exclusive to this collection, so users of other gaming collections can still find more games to satisfy their gaming needs.
