I'm not qualified to gauge the technical bits but this has fun elements that appeal to me.
The elevation changes are the best I've come across in any sim. The Belgium Forest version of Eau Rouge is epic as you stare into the sky. And the drawing distances, which appear huge to me, make it feel very real. Also looks great to me.
Getting a new version every couple of weeks is exciting. A new present every couple of weeks for 10 euros
The Cateram is like not other sim version I've tried. When you get in a tank slapper its very, very difficult to get it outta of it unlike other sims. It could be vague as Shark suggests or maybe realistic? I've honestly got no idea but this makes me feel human where other sims can make you feel like a driving god. I quite like being hit around the head occasionally.
Less fun is the lack of opponents, no online racing is a let down, and lack of 'normal' features so far. Bear in mind this is all very beta. Some fun and pleasant suprises to be had
