The games that I've played the most the last 2 years are Battlefield 3 and Dota 2. If that's what you mean by hardcore, then those are the ones for me.
Yeah idk i just never really liked Dota2. The map was super dark and just kinda meh... Plus i had LOTS of friends at the time playing league that were constantly harrassing me and telling me to download and play league. So i did... And i gotta say... If you played lots of Dota or Dota 2 once you get used to the changes you are pretty much all set to own face in LoL. Its SOO easy, yet still fun.
I mostly play RTS and Moba style games now adays as well as ALOT of benchmarking. I do play other games however such as the witcher 3 and Crysis 3, and recently Ashes of the Singularity. I love gaming on the cutting edge and refuse to accept any compromises. Proud member of the Glorious PC Gaming Master Race. Long Live SHIO!!!!
