Sometimes a good HOG is a nice brainless diversion and I thoroughly enjoy them. I have several of the older ones from Big Fish which I frequently play. Through painful experience with the new ones, I have found that I loathe the insipid comments, horrible voice acting and other other intrusions. However, many others enjoy them, so I'm not a good judge!
What I would do is to peruse a few that look interesting at Big Fish and then download a trial version to see if you like them.
