I don't know about the PC version, but yes ... the game is incredibly buggy. From people being chased freezing every time I tried the mission, to awful clipping and pop-up, this game doesn't feel AAA at all.

Outlaw in the Atari.

Lara Croft, guardian of light
Rayman
X-men legends or Marvel ultimate alliance
Lego games are fairly decent.
Portal 2 is a good choice too.

Skyrim
After I lost my 100+ hours save I realized I am fine not knowing how it ends.

Walking dead is heavily spoiled. Don't listen to it if you want to avoid them.

Yes, most of the chapters are pretty light in spoilers. I would avoid the day 1 and the one about dlc that should be on the game.

Omega is pretty isolated. You can play it at any point, really.
Leviathan is pretty heavy storywise, so I would advice you to play it after Tessia.

Ryan is the best. And I was surprised about Patrick. I think he did better than the rest.

I am currently only playing on my PS3, but yes... PC is the strongest contender.
