1. Diablo 2: Lord of Destruction

Thanks to the modders for keeping the game current!

Some might question my labeling Diablo 2 as "the most played RPG of all time", but let me explain. Keep in mind, this is not for MMOs and Diablo 2 is not an MMO, but it's on the same level really. This is a game that came out in 2000 and was the RPG to play in multiplayer, until World of Warcraft in 2004. That means that the majority of PC gamers we're playing this for four years straight.

Even after World of Warcraft came in, most of the fans did not make the transition. Instead, they opted to turn to the modding community (and there was a huge modding community for this game) to enhance their gameplay. Thanks to that, this game had a massive player base for almost a decade, until finally dying down.

Then came Diablo 3, which was love-or-hate and had certain players rewind and go back to previous titles. Seriously, for a single player game, this is insanely impressive staying power (matched only by MMOs)!  

All time is a long time. Some games have stood that test, some were dominated by newer releases, while others were completely forgotten. Though the titles listed here are the most played RPG games in general, that doesn't mean they are the ones each of us played the most. Everyone has a favorite right? What's that one game you always kept coming back to, or never put down?
