Less nice technically or socially? Speaking as someone who has played countless hours of competitive video games in my downtime after work, I assure you that, socially, 'less nice' is a charitable way to describe gaming chat, devolving into a constant torrent of abuse and harassment depending on your skill level, the sound of your voice, and the Dunning Kruger level of yourself and your other team members.
Discord is already being heavily used in the less nice gaming communities revolving around cheating, compromise/hacked accounts (not just game) selling/malware and game related phish/keylog.
But incidentally the same people selling hacked spotify and netflix accounts also provide "support" over skype, so opsec, meet window I guess
