So I've only had the chance to do about 3 races so far. I like it, but I don't yet love it.
First off this does look nice, the graphics are clean and smooth, no complaints there. The only IAP is a full unlock, no complaints there. There seems to be plenty of content, and from what I can tell you can still race a championship in the free version, but you miss out on qualifying sessions for each race, the full version unlocks qualy. The reason I only like and not love yet is the feel, or lack thereof, from the bikes on track. I get an impression of the bike just kinda floating on track rather than having any real weight or grip.. It's still ok, but there's no feeling of feedback from the bike. There are plenty of steering options and a few tweaks to handling such as auto brakes. Overall it's a great addition to the moto iOS race scene, I just wish it felt a bit better in the handling/riding area.. Mind you having said all that I've yet to really flesh it out.
