I am new to the whole F1 simulators, however my knowledge of racing sims is quite high. I was just expecting an okay racing sim here. But what you actually get is a really close fine tuned simulator that is gonna give you hours of fun. I know many people moan about how sims are boring, I was the same, but this game is completely different. You can have the realism as high as you like. With all driver aids off and all HUD mods off, and of course a decent steering wheel and pedals setup, it's like you're racing the real thing! I'm only on the third weekend of the season after a week of playing it since I'm trying to learn the track. I love how you start low with say Force India, ending up with a contract deal with Red Bull or who ever. To all those GRID fans out there, no you can't go round a corner a million miles an hour whilst drifting. You make one tiny mistake and BAM, you're either the wrong way or into a wall. The damage is awesome too, really makes you try and set each corner up, as you don't wanna end up in a wall on your last lap of 20.
The only downside (if you can call it that) is that you have to really learn the track before you race it. Obviously coming from say F1 2010 or if you're used to the track layout it's gonna be easier, but for me it's impossible to put a good time down in quals. So I end up using all of the practice time to finally grow accustomed to the track. It's all part of the fun personally, but I guess some would grow rather tired of this.
In terms of graphics, they are pretty good. Nothing amazing, i think if anything it's a downgrade from 2010 but it's not the most important part of the game. You tend to forget about graphics when you're concentrating so much on the track layout. At least they have better graphics than the console equivelents :3
In all a fantastic game that every racing fan should at least try, even if you've gotta play it on a console ;D
