The Sly Collection contains
Sly Cooper and the Thievius Raccoonus,
Sly 2: Band of Thieves and
Sly 3: Honor Among Thieves, all three great stealth-platformer titles that featured one of the PlayStation's iconic characters during the PS2 era.
In the series' first game, Sly, Bentley and Murray work together to try and claim Sly's legacy, a book called the Thievius Raccoonus. This tome contains his family's history and is used to teach each generation how to become a master thief. Unfortunately, the book was stolen and torn apart when he was young and Sly means to assemble the pieces and claim the skills that are rightfully his.
Band of Thieves grants players the ability to control Sly's two friends. Where Sly is all about sneaking up and being stealthy, Bentley has some ranged attacks to take out his enemies. Meanwhile, you use Murray to charge in and use brute force to clear a room. The three characters really have different enough gameplay feels to keep things fun and different.
Sly 3: Honor Among Thieves keeps the series going by giving the gamer more characters to play as and also making both Bentley and Murray a bit more useful. Part of that added usefulness comes from the fact that Bentley is now wheelchair-bound, but of course, Bentley being Bentley, his wheelchair has a few added features that still makes him a formidable member of the team.
What is great about these three games is that it manages to hold onto its core gameplay style all the way through. While you can play some characters in a different manner than Sly's stealthy style, the feel of the game doesn't ever really change, not even when they keep tacking on playable characters, mini-games and other features.
