I just want to start by saying that you should not listen to the reviews saying negative things about this game. All of them have the same thing in common. 0.1 hours played.
High Octane Drift is very fun and easy to get a handle on. It definetly is not like any real drifting, but that is almost the beauty of it. It's a new mechanic to learn and it's fun to practice it and get better.
The customization of cars is awesome. There are not as many cars as I would like, but it's still in development. Modifications are very good. There are many different options with pros and cons on each part. I would like to see more body kits and exterior modifications, but again, I still have hope for the future.
When first starting there is a tuorial of some sort... For me it was buggy and not helpful at all. I did resort to asking other people online (Mostly everyone online is pretty cool too) about things and using Google. After playing and messing with things on my own, it came along pretty quickly.
Microtransactions are 100% not needed and not intrusive at all. You do get an edge by paying real money, but name a game that you dont get an edge by paying.
There is also a mechanic where you must repair your vehicle, buy tires, buy fuel, etc. At first I was very turned off by this, but it is not bad at all.
Overall High Octane Drift needs some work to be better, but being in open development means they will gradually improve! I'd definetly say play this game and spend at least 30 minutes in it
