Just in case you missed this
The Sim Racing Tonight (
www.insidesimracing.tv) guys could drive it (a bit)
Unfortunatly they don't show a real race, just practice laps and how the web based interface of iRacing looks like.
Take a look here:
http://www.youtube.com/watch?v=zbAC-PV3lZI&eurl=http://insidesimracing.tv/index.php?option=com_content&task=view&id=148&Itemid=206There are still lots of unanswered question for me
(No side view / side mirrors? Only cockpit view? ... etc. etc.)
and things I really don't like
(no skinnable cars or helmets, no pickup racing with friends, every new track [you need to buy them] when your license goes up 15$ to 25$... etc. etc.)
So it's defnetly not something you can enter and just race for fun for an hour in the evening
(as every race etc. will have influence on your rating/license/rank and will follow you forever in the stats)
Anyway I think there is no other way then testing it yourself to really judge about it.
