There are plenty more of all the things that made the second game so incredible. And of course, both in terms of gameplay and narrative, the third instalment is even more ambitious. This of course allows for such incredible levels as becoming pirates and sailing to various islands whilst looting other ships - almost a whole game in itself. There's also a multitude of new characters (and even returning favourites) which provide even more diversity in gameplay. My main criticism, however, is that the game feels a little bloated and somewhat unfocused when all of these elements are thrown into the mix, sometimes it works and sometimes you just want to go back to just being Sly and doing the Sly stuff!
Overall, it's a solid sequel and a well rounded finale to an intended trilogy. (I wouldn't say the fourth game is a total waste of time, it just doesn't have the magic of the Sucker Punch classics).
