By the time you do every possible route for this game and every possibility to passing a level and everything, you will be playing until like Splinter Cell 2 comes out or some shit because you can't outdo it...and plus...you should master a game before you get bored with it...as in with this game...don't use the gun at all...just grabbing/knocking out/punching...sneak up on em like a real stealth man instead of sitting in a corner of the courtyard on the second mission and going PAP PAP PAP at the 3 guys...yeah any of you who have played and are reading this , you know you fuckers did it lol ... but yeah this game is definitely worth it. I love it.
