So Rocket League has been out for about 10 days now and it can easily be said that it has been a smashing success up to this point (network connectivity issues excluded). The thing I'm wondering is where this thing will go from here, but first I thought I'd show some stats of its success.
Metacritic score of 85 with a user score of 9.1 on PS4 and a very positive score on Steam with almost 3700 reviews.
A 5 Star score with about 27k votes on the US PS store: https://store.playstation.com/#!/en-us/games/rocket-league/cid=UP2002-CUSA01163_00-ROCKETLEAGUENA01
And another 5 Star score with almost 37k votes on the European store: https://store.playstation.com/#!/de-de/spiel/rocket-league/cid=EP2002-CUSA01433_00-ROCKETLEAGUEEU01?utm_source=google&utm_medium=cpc&utm_term=ps%20store&utm_campaign=PX+-+PlayStation+-+Brand+-+DE&EMCID=GM300000_store
It also got a 9/10 from Angry Joe yesterday
Steam sales are rising steadily with currently over 20k sales a day: http://steamspy.com/app/252950
PSN sales are of course more tricky to find out, but it stands to reason that normal sales of the game should currently be rather low since it's free on PS+ (which is not bad for the game, since it gave it a popularity kickstart)
What else... the Rocket League subreddit has shown very healthy growth since the games release: http://redditmetrics.com/r/RocketLeague
And general popularity of Rocket League posts on the site has been pretty high as well.
The same goes for Youtube, it's not uber huge (yet) but it's getting good amounts of views: https://www.youtube.com/results?search_query=rocket+league
Finally the game has even been acknowledged as an official eSport already, something that can really help it in the long run: http://play.eslgaming.com/rocketleague
Bottom line is that it's doing well, the question now would be if the game is just kind of the flavour of the month right now or if it will enjoy longtime popularity and relevance and if Sony would acknowledge that possibility and try to make use of it by for instance entirely blocking an X1/Wii U/NX release.
In my personal opinion this game has all the pieces in place to become an extremely successful and longliving game: It is based on the most popular sport in the world, it is easy to pick up but challenging to master, it can be an extremely competitive game or one that you just play for goofy fun with friends and it comes across very well even when only watched, you can easily tell that the game is fun and you can also tell how challenging some of the stunts that some people pull off are making it a very ideal streaming/youtubeing game (imo this is a very important point). Thanks to the PS+ deal the game has, as already mentioned, also gotten a massive kickstart that just further helps its popularity.
Now I'm not saying people are buying PS4s for this game now (at least not in any meaningful capacity) but if this game continues on its track it can become a huge selling point in a year or so, if Sony manages to completely lock down that exclusivity.
What do you think? Is Rocket League a new evergreen or just a fad?
