You know, for all its flaws - and the game had many - I still enjoyed Call of Juarez: Bound in Blood. So I'll be dusting it off now that a level creator is on the way.
The world builder will be available in two modes: a "simple" mode for basic level creation that's full of tutorials, and an advanced mode, which "boasts full capabilities of the professional tools used in the development of CoJ: Bound in Blood".
Which means you can cut out the rubbish parts of the game, concentrate on the parts it got right, and build entire levels around those good bits. Which is always a welcome move from hit-and-miss games like this.
