The disc version SHOULD come with the first game added in, while the download version should be the second game only (dunno if there will be a difference in price, or if the first one will be available as a separate downloadable title). There should be an indication on the box of the inclusion of the first game (if the PAL cover is like the American one, that is, and the one linked is only a placeholder).

(Spam filter doesn’t let me link the relevant pages, but you can find more about that on destructoid and vg247
