I'm a new PC gamer, please recommend me some classic games

[shakarak]

I also game on Nintendo and have every system up from N64 and handheld.  My only other console is PC.

I game on these systems like you to get the best of both worlds. My recommendations and favorite PC games that I would immediately recommend you play are:

I would either start with the Witcher 2. The Witcher 3 is the best but the Witcher 2 is a great game that still has great graphics and a strong story.

BioShock Infinite: The game's story anod ending will melt your face. Skip 1-2 (although good games) don't hold a candle to 3.

Civilization V: if you like Strategy games or Europa Universalis IV if you REALLY like strategy games.

Starcraft 2

Counter Strike Global Offensive: If you enjoy polished competitive gaming (it has a learning curve).

Metro 2033 and Last Light: Awesome atmospheric games that look great on your new rig.

Pillars of Eternity: If you like deep RPG's (the game I'm currently playing).

A couple cheaper Indies you can pick up that are amazing are Limbo, The Wolf Among us, To The moon.

Feel free to add me on Steam :)
