Well I was also reluctant to ger rFactor as I was only intending to play F1 mods, and was of the opinion that the handling would be the same type of thing as GP4, and that the weakest link would be my admittedly cheap steering wheel - as it was with GP4.
With GP4 it was so crap that I never played a single full race with the wheel and pedals.
So, got rFactor this week, started downloading mods, F1 only as this is the only racing type I'm really interested in.
Played a bit with keyboard, which was alright as you also have more control with it in this game compared to GP4.
Thought, maybe I must dust off my steering wheel and see how it feels.
WOW!!! It's just so much more controllable, already did a 58 lap race at Bahrain with Vettel in the 2008 mod, admittedly only 80% AI strength, but the sole purpose of this race anyways was to properly for once get used to my wheel and pedals.
Started out with 1m39-40s for most of my first 2 stints, later in my second stint was late 1m37s to early 1m39s. Last stint was consistently in the 1m36s with what was for me a monster lap of 1m35.6s, which was an adrenaline rush of note. Only had one spin the whole race when I was trying to show off to my fiancee :P
Finished lapping everybody twice in the end, but as I said this race was like a practice run and it got so easy - if you know what I mean, not like driving with my eyes closed, but more like I knew exactly where the perfect braking sports were and my accelerator control was honed in better - to pump in the faster laps that lapping everyone twice became inevitable.
Another thing that I really enjoy was the use of the ENTER key to scroll through the various sceens/options, i.e. damage to pit strategy to gaps to laptimes etc.
The ability to pause and decide and apply your following pitstop specifics is one of the topmost features of the game to me.
Excuse my enthusiasm but that was just such an exhilirating experience. I love this game. I would recommend it to anyone who is considering buying it. That's the way a racing sim is supposed to be.
The only drawback seems to be the AI, which doesn't seem to know the human player is even there, I can pass them without a 'Vettel' move. But it's still awesome other than that.
Also like the fact that my relatively low spec gfx card can play it at Ultra graphics.
If you are even considering buying it, do it. You won't be sorry.
