While we're doing well adding games in general to MobyGames - see above graph where red is # of approved items, particularly the right hand part of it which shows our all-time record is in 2017 - we've been slowing down a bit in the last few months.
Part of the issue is that there's SO many Steam games nowadays, that it's difficult to work out what to add, honestly. One method I've found helpful is to look at SteamSpy's sales countdown for a particular month - like January 2017 - and then check to see which games we are missing that cost more than USD $5. In many cases - like Avorion, which has more than 100,000 players, we've got it added. But in others, not so much.
We'd love to get to the stage where all Steam games that cost more than $5 and have more than 5,000 players are documented on MobyGames, but we know that's a tall order. Don't forget that you can use the Entry Helper to enter these games!
Also, Alaka now made it to 50,000 points (very impressive!), and Vedder is now at 25,000 points - also a great total, which puts him in the Top 50 overall. All of these folks are doing amazing work contributing historical and current data to MobyGames, and wanted to thank them here - keep it up.
This year alone, he's added over 1300 Critic Scores, as well as over 600 promo images, 55 games, nearly 400 release infos, and a whole bunch of other stuff. The fact that we have such diverse reviews, even for obscure games, across many languages - and with sites it's difficult to grab scores from automatically - is down to users like him. Kudos, Sir!
