I see your into those kind of games you should get diablo 3,world of warcraft,and fallout they are all open world kind of games diablo is just like world of warcraft but have a different platform,classes,and weapons I play it on my xbox but on pc its amazing!!! Fallout is set in the future when the world has died to an waste land and you have to run around defeating crazy bosses and enemys from robots to lizards. I most likely prefer Fallout New Vegas for the best gaming experience.
Diablo 3 is an utter failure.
Anyone who played Diablo 2 knows that.
People who play Wow think its the greates thing on earth.
Diablo is Diablo and should have nothing to do with Wow.
If you haven't tried Path of Exile yet and you liked Diablo 2, you should probably do so. It's basically exactly what Diablo 3 should have been. It was made by a group of hardcore Diablo 2 players. The dev team is amazing and interacts with the community all the time. Best dev team I've ever seen in gaming by far.
Oh and it's 100% free to play with no pay to win aspects whatsoever.
