PlayTogether

Type /gamesincommon in any text channel on an enabled server, choose how many games you want to see and how to rank them (or hit tab a couple of times to choose the defaults), then tag anybody you want - up to 8 Discord users! (All tagged users need to be online, and they must authorize the bot to pull their linked Steam accounts. Make sure your Steam profile isn't private!)

Enter /gamesincommonhelp for a complete breakdown of the options.
