Graphics...smaphics. This game is completely immersive, easy to get into and downright fun!
Well, first off, my PC is a few years old, so that is to my benefit, second, WHO CARES?! IMHO Substance is worth far more than style, the graphics are functional and not really that bad from what I've seen elsewhere.
I've played a few hardcore racing sims in my time (The old papyrus sims IndyCar racing II and Nascar Racing, and more recently Nascar Thunder 2004) and none of them were as easy to get into and downright fun as this sim. It's a joy from start to finish, from practicing against yourself to the full races.
The AI is the best I've seen, with your CPU opponents constantly jockying for advantage.
From what I can tell so far the community is very friendly.
I was able to be pretty competitive from the start (granted with the novice settings an a 85% driver difficulty) and using the Mini's. It's more fun, and the short races, short and sweet, it's perfect for those that don't have 2-4 hours for a full race in another sim.
I do hope for a new indycar sim in the future, but for now, I am joyfully playing Race 07!
