I downloaded Rocket League the day it went for free but I wasn't interested in playing it for some reason.
I decided to give it a try some days ago though, and I got hooked immediately!
Rocket League is football/soccer with cars... and that's pretty much it. It sounds very simple, but it's executed so perfectly and it's undoubtedly one of the most enjoyable games I've ever played.
Aside from being fun to play though, Rocket League is accessible to everyone. However, the player's skills and experience are very important in Rocket League because there aren't any stats in this game.
Also, there's a fair amount of different game modes, the customization is cool, the music is fine, and the visuals are pretty good but not anything special.
Surprisingly enough, I don't have anything negative to say about this game; it's flawless.

Pros:
+ Excellent execution
+ Addictive and accessible
+ Nice amount of content
+ Car customization

Cons:
- None

Content: 7/10
Music: 6/10
Graphics/Audio: 7/10

Final Rating: 9/10
- Amazing -
Rocket League is all about pure fun, accessibility and skill... and it excels in every way; it's so goddamn fun to play, it genuinely makes me happy.

Do I recommend it?:
Hell yes! I'd recommend Rocket League even to people who don't play racing or sports games.
