I suggest you read Gjon's post before buying. FYI I'm not regretting getting this at all. Like I said before it has tonnes of potential. If you're looking for Dirt3 graphics you're probably going to be disappointed. For me they are good enough.
Tried it out for a while, and I really liked the feel of the physics. No idea of how accurate they are but it felt very "dynamic" and natural, none of that feeling of driving an excel sheet as in previous ISI sims. Everything else though is not so impressive, that is, pretty much the same as before. With H-shifter I can still just ram in gears without ever having to use the clutch or rev matching or anything. Damage is just larger parts flying off. UI has a different look but everything is the same... And the graphics. Why cant they hire some competent artists to create some high quality models and textures? The historic spa track looks decent, but almost everything else is just awful for something released in 2012.
This is what I put in the thread on iR forum. I quite enjoy it. However I'm not a guy who cares about the UI, graphics etc (the graphics honestly don't look that bad). I'm just a person that likes to drive a car and feel it on the road, and the dynamic changes in rF2's enviroment makes it even better IMO.
I would also comment that this is the only sim other than LFS with FFB I actually like. It doesn't translate the g-forces as much, which I kind of miss, but it's extremely helpful and intuitively-useable. It does jitter way too much when you go off-track, though. I'm a huge stickler for proper FFB and it can make or break a sim for me, so I thought I'd post that if it was of interest to anyone else.
Apparently it is cheaper to buy a lifetime lisence separately in addition to the normal 12/18 month lisence (buy normal lisence then later buy the lifetime addon) instead of buying lifetime lisence on the first time...
