25 Games That Can Give You Over 100 Hours Of Gameplay

6. Deus Ex

As one of the first games to truly react to your every move (or at least give the impression of doing so), Deus Ex is often a byword for quality and innovation within gaming. This isn't purely a case of quality over quantity though, as Deus Ex has a massive lifespan as well. Whilst it doesn't have the longest story in the history of the medium, when you factor in just how damn tempting it is to try alternate decisions in multiple playthroughs, this is one game that proves very hard to put down indeed.
