Good games to play on PC?

The past few games i've been playing are Team Fortress 2, Payday 2, Minecraft and Grand Theft Auto IV. More or less, I've gotten bored with these games, I got around 500 hours clocked on Team Fortress 2 and Payday: 2, MInecraft, there's nothing new to do in my survival world (earned all achievements), and I've just gotten bored with GTA. Anyway, are there any titles anyone would recommend to me.

P.S: I'm not really a Call Of Duty Fan. I have Battlefield 4, it's very average. Also, I play on PC.

I like Skyrim and Mass Effect (especially the second Mass Effect) for pc probably the most.

There's also Jazzpunk that's different, but pretty funny, but different.

And Vampire: The Masquerade is an oldie, but a goodie!

I love interactive games, so I may have different interests than you do. You could also try an RPG like Star Wars the Old Republic. It's free unless you want to subscribe.

Shadowfall… Try it… TRY IT!

Devil May Cry 4, Assassin's Creed IV Black Flag & Far Cry 3

The only thing I would recommend is Crysis, (yes I know it's a shooter, but it's a decent one at that).
You can get Crysis 3 (if your PC can handle it).

These are great games:

Half Life 2
Portal 2
Skyrim
Dota 2
Smite
