I have nothing but good things to say about both MovieCat! [Free] and MovieCat! HD [Free]. There are trivia games of all sorts on the App Store, as mentioned in my initial review of the game, but I've yet to come across one that has as much personality as MovieCat!. I'm not sure if it's the fact that every part of the game is absolutely loaded with cats, or that the questions included seem to span everything from questions everyone would know to extremely obscure factoids for movie buffs.
The included content in MovieCat! is incredible, and there's even an optional 99¢ DLC pack with even more. This add-on is by no means required though, as it took a considerable amount of playtime before I even started running across that many questions that I've seen before. If you like movies, and cats, it likely will only take you a few seconds with the game to see why I included it in my list of favorite games of 2010.
Don't miss this game while it's free, and even if you do, it's totally worth the asking price once this freebie promotion is over.
Note: This price change seems to have just gone in to effect. If you don't see it as free yet in your neck of the woods, give the App Store a bit to update its pricing.
