One of the best RPG's I've played, Dark Souls is a challenging game that really rewards your progression. With difficult boss fights, stressful PvP and loads of ragequits, Dark Souls will consume you from within and steal all your time.
The only downside is that it's a bad port and thus needs some tweaking before it runs smoothly. Once you've tweaked it though, you'll get rewarded well.
