Not sure how you can call Farcry 2 bad, but each to their own I guess. It was a little repetitive, but there were lots of great aspects too.
So far, I've only scratched the surface of Farcry 3, but it is starting to grow on me. The scenery is very nice, and there are lots of animals, from tigers to crocodiles, sharks, monkees, Comodo dragons, wild boars and so on, so very much a new venture in that sense.
I've not bothered with multiplayer yet, but so far I'd say it's a great game if you enjoy being chilled out in a beautiful place, with no need to rush anything.
You can get it here for a bargain price of only £22 http://www.simplygames.com/search.php?k=far+cry+3&pc=All
