WEll, after running the demo for a few days, I decided to order the real deal (UK version) from an Ebay source.
GT4 is a game.
GTR is not a game.
Sure, GT4 has a bunch of tracks and ~700 cars. But IMO GTR trumps this by giving full access to all tracks and all cars right from the get go.
YOu wanna jump in a Saleen S-7R as soon as you start playing, well good luck.
YOu wanna drive Monza or IMola or Magny-Cours at full bore with a race prepped Mucielago, have at it.
Just don't think that its a game. THere are no "700K$" Tricks or "$/minute" racing strategies to unlock the black beauties.
What there are,are a huge amount of setup options for a given car, radiator vents, tire air pressure, seating position, a customizable MOTEC display, to name a few.
This is a SIMULATOR.
And because its based on other sims, there are mod tracks and cars readily availible online.
Last night i downloaded Watkins Glen and IMola. I also downloaded a BMW E46 M3 car that is a fun drive no doubt.
I plan on downloading a few more tracks and car skins.
I play with a Logitech DFP using 4.6 Beta drivers. FF is top notch. More accurate than GT4, IMO.
My PC is a P4, 1.8Ghz with 512 RDRAM and a 64MB GeForce4.
I just purchased an additional 512 of ram so I will soon be at 1 gig. Next upgrade will be vid card then mobo.
If you are a DRIVING nut and follow motorsport at all, I highly recomend this SIM. Honestly, im not real interested in playing GT4 right now. That is how much i like driving in GTR.
As always, YMMV.
