i agree with these other guys, you have to decide for yourself. I started off slow with a 3 month trial period. Then i was out for about 6 months. It was at that point that i had some extra money and really decided to give it an attempt. You can't judge the road racing on the solstice. If you think about it, this is where every iracer has to start, good or bad. You WILL find a lot of bad eggs out there, but it could also just be someone who's trying to learn. If you stick with the solstice though and eventually work yourself to a D liscence (if you reach a 4.0 safety rating you'll auto rank up on the spot) than you will be able to choose from the jettas or the skip barbers. I currently am running the skip barbers and i absolutely love them.
On the oval side the legends are enough fun to keep you entertained for a while. Again, you'll encounter some newbies, but stick with it because as you get better liscenses, you'll race better drivers. I'm currently about to hit my B class liscence in ovals where i'll be able to race the nationwide cars. As of now i'm in the Craftsman Trucks and they are fantastic.
Iracing is great because it takes your irating and sticks you with guys who are on the same level. This gives you a shot to win every time. The other day in the skip barbers i started last on the grid (15th i think) and stayed clean. Once the 1/2 hour race was up, i found myself crossing the finish line in 1rst with my first skip barber win! Little things like that keep me running it, so much so that i ponied up for 2 year subscription which saves you about half what it would cost if you just paid month to month.
If you've ever wondered what it's like to sit behind the wheel of a real race vehicle, this is about as close as you'll get. That's why it costs money
