Amazon and newegg both have it for $39.99, is it worth picking up at that price? Gran Turismo 4 was awesome but I haven't played in probably 8 years.

Looks like GT4 got better reviews than GT5 did. But it's your money and not mine, so buy it.

GT3 was the last one I played.

Since I have a 360 instead of a PS3, I have to admit I know little about this one. I vaguely recall reading that the one main flaw people had with 5 was along the lines of it taking a longer-than-usual time to build up a good garage and get into the bulk of the cool racing. I don't know if that means license tests or that it takes longer to build up money or that you're less likely to win a car from a race/series that will CARRY you to a lot of wins.

Sometimes I think about picking 3 back up or maybe buying 4. But I just don't know that I have the patience to sit through all the S-level license tests (the ones where you have to run clean laps of most of the tracks) again. Which I'd have to do even with 3, as I deleted my save data from when I was running through it.

Yes, Very worth it.

Yes, Roommates bought it before break and it was terrific.

I would say its incredibly worth it. Hook it up online for the updates to race in the seasonal events so you can win an insane amount of money. B-Spec is a lot more fun in this game IMO.
