Just go to the 'Featured Game' wizard & enter a couple of paragraphs about why you love one of your favorite games in the MobyGames DB, and hopefully we'll go ahead and featured it!
In addition, we'd love a more regular supply of reviews (which are featured prominently on the front page right now, too!) Just go to a particular game and click on the 'review game' link next to User Reviews & you're set!
In particular, most excellent MobyGames user Kennyannydenny has been working on adding achievement art (the pictures you get when you complete in-game milestones!) for a number of popular PS4 and Xbox One games, including for Project Spark, for Fallout 4 (scroll down!), and for Minecraft: PS4 Edition.
Turns out there's a lot of original, hi-res art associated with achievements, many of it interesting and not available easily online unwatermarked. So chalk this up to another win for MobyGames!
