I gave up on the first one when I got to the endurance races. Two hours each and even then I might end up losing? No thanks. So I never went back to the series. Which sucks because I was way into it up till then.
But it is a sim game; never claimed to be anything else. There's a million arcade racers for people who don't like the tedious side of things.
And the first game most certainly did not look like crap when it was released.
