Extremely satisfied. More than I thought I would be, and more than most games I've played this year. The breadth of content, tracks, features, events etc is offering me incredible play time and value for money, and honestly I've already had some of the most memorable experiences in the game, even though I'm not even half way through it (still have put in 50+ hours mind).
Playing with all HUD options, driving line, assists etc off using a steering wheel, it's a superlatively immersive experience. Just me, the car (cockpit view), opponents and the road. Nothing else in the way. At times, it's stupendously realistic in atmosphere and feel.
Don't get me wrong, certain issues and physics or AI mishaps still occur, but they are minor in the grand scheme of things. Many regarding physics can be ironed out or tweaked with custom settings for me.
The real beauty has been in the unique experiences, the X2014 Jr championship, the Goodwood challenges (holy crap that X2010), coffee break challenges, driving an old classic slip sliding at the brink of the edge during a sunset, kicking around a custom tuned behemoth at night, Brands Hatch, Willow Springs, Matterhorn (so precarious in cars that like to spin out easily), Nurbergring, La Sarthe, Spa etc, driving at break neck speeds at night below a stunning star and moon lit night sky and so on and so on, hell, even the the moon buggy was awesome and totally bizarre.
When it clicks in GT6, and everything aligns in harmony, the experience is truly breathtaking and joyful. Thankfully there's been a lot of those moments, and tonnes of variety to keep things entertaining and fresh.
Hope they keep updating with new Seasonal events regularly as well, because I've really enjoyed them. I'm also super pumped to see the rest of the Vision GT cars. What a truly amazing addition. Even the concept art attributed to the different manufacturers is beautiful. A true feast for any car enthusiast or designer!
