Is the primary purpose as a recommendation engine? Is it a reviews aggregator? Is it a "do everything thats already being done elsewhere, but do it in one place" website? What does RAWG do that Steam/Metacritic/Gamerankings/gaming websites don't already do? I guess I don't see the value to spending hours making a unified list of all the games that I already own and that I already know that I own, when having that final list doesnt seem to provide any new utility.
I just stumbled over this website and after a few minutes already recommended it to a friend. Looks very promising, especially the "development team"-section is something I'm interested in. This section and the knowledge about who wrote and created games is most often overlooked
Nothing more to tell: the idea to have some place where your games info is stored and all games info is stored is great. Last time I checked, I found no use of it for me.
