I am a massive F1 fan (*sob*, Webber leaving F1...) and while not perfect, this is a pretty cool game. I bought all the previous versions and yes, if you turn the difficulty way down it does feel arcadey. But try racing a full 100% race at top difficulty. You will fight for every position!
Let's just hope they polish up the PC version properly this time around, 2012 was a complete disaster and the patches made it even worse. So I got it for the console, but I wasn't really impressed, they made it a lot more arcade-ish, and that's what's slowly ruining the franchise for me. Codemasters did the same thing crossing from Colin McRae series to Dirt.
Also, does the game seriously look that awful or is the video compression used by GS so poor? Watching in 720p is more like 360p.
This is a must buy for me. I'm a F1 fan and codemasters F1 series of games have been a light in the dark for console F1 gaming. Not 100% sim or 100% arcade their F1 games have been solid.
