This was my initial impression:
Good modern FPS for casual player. Keep in mind that it still have tons of bugs, but once fixed I think this game will be somewhat good for most of the players.

My updated review:
After considering it again on what the game has become (lack of updates, plummeting player base) and dev responses to criticism by its own player base, I can pretty much recommend to not buy this game on this current state or ever (as i didn't see any hope from it really.)

10/10 for F1 fans. Not too difficult to play compared to other simrace games, the level of difficulty can increase quite well if you are a hardcore simracer.

ps: Don't expect this game to be one of the best physics simrace games (you might have to play iRacing or Assetto Corsa instead).

9/10 for me:

Worth to buy and really enjoyable especially if you are saint seiya fanboy.

This game is easy to learn but not really hard to master ( joystick / gamepad recommended )

10/10 make me addict.
