I was lucky enough to try the game before considering purchasing. As someone who really enjoyed the 2010 experience but disliked 2011 and 2012 (didn't play them much after release), here are my thoughts (yes i purchased based on my trial)...
Firstly, I enjoy Sims more then Arcade and this game defo falls over the line onto Arcade but I have to say...i'm really enjoying this game!...and i'm most surprised. The handling is ALOT better, still a bit wishy washy but a big improvement. Struggling with wheelspin out of slower corners and my arch nemesis, oversteer...really struggling in fact but enjoying the challenge none the less.
Love the strategy with fuel, tyres and weather. Trying to beat your teammate can't be overlooked either.
The AI seems MUCH improved. Much faster, they move off racing line when on an outlap or inlap, they slow when appropriate and I've noticed several times they speed up to get through the upcoming corner then pull over and slow, all to eliminate or dramatically minimize your lap disruption. They're actually thinking ahead now.
The sound is awesome. Gear changes and cars just in front are my favourite sounds.
My Career 2 races in has been fantastic fun. The pressure of Q is a buzz and the race is even better.
Yes there are/will be bugs (I've not noticed any...yet) but I feel they are more online related. For me, the fact that you can cut corners and smash into other cars with little or no damage et cetera, has no impact for me as I don't do either of those things (and either do the AI). Maybe once I experience a big bug that ruines a race I will feel differently but so far so good. I have faith that CM will fix any race ruining big bugs (cough cough). So far so good.
In summary, for those wanting a really good offline modern F1 racing experience against excellent AI that looks and sounds very good, consider this game, especially if you like/love modern day F1
