I think the majority of users, like me, moved to ERA (and is active there), because whole communities and the users they like to talk to also moved there. Off-topic got nuked, communities, for my example, SteamGAF, moved to Discord. Some people found themselves on GiantBomb, WayPoint and Slaent, but used the forums to get in contact with their GAF communities and other GAF users. Like I found myself on WayPoint, but got helped there to find SteamGAFs and GAFs Discord.
Many of us had nowhere to go, so ERA was our best option to collect all the communities.
Im on ERA for the PC gaming thread, the game OTs, gaming news threads and the general funny/weird/joke threads. Is it toxic? Maybe, but ERA fills the forum needs that GAF gave me.
I need the PC gaming thread for example, but SteamGAF thread here is dead and the users I talked to moved to ERA.
SteamGAF is like Asgard, it's not a place, it's people. If PC gaming ERA moves back here on GAF I will do it too. The people is more important than the place.
