I'm looking for a racing simulator. It doesn't need to be anything fancy, the only requisites are:
- it should be 3-d. By that, I mean that it shouldn't be tiny cars on top of the aerial view of the circuit layout.
- it must accept custom circuits, as I want this simulator to learn a karting circuit in my town
So, that's about it. Since half an hour in the karting circuit is 45 euro (about 60 usd), I would like to be able to learn the circuit so that I know what's coming and where should I go fast right away.
Thanks in advance!
