I'm happy to hear that. I was playing 2014, but now I'm trying to get more into 2013 but their both fun. 2013 has more race winning cars, Red Bull, Ferrari, Mercedes, Lotus, even McLaren is fast for the human driver. The AI McLaren isn't as good as human McLaren. Closer cars, different winners, good championship battle. It makes playing a season more exciting. F1 2014 races are almost always won by Mercedes. Even as the player it's hard to win in a non-Mercedes car.
Ofc, I play it since 2014. I'm on the 13th season and I change cars liveries, tyres and innovations every time! I love it, handling looks good (I play with gamepad), good IA skills and good graphics (with the rights improvements). At the time was the worst game outdated for codemasters, but you know, things get well as they old.. and this game is like red wine!
