Well, it's actually now "Steam+", meaning "Steam-Plus" other stores.
Explanation incoming.
We (the CAG Posters that post a lot of PC deals & regulars posting in the Steam Deals thread) did also have threads for IndieGala, Gamersgate, Groupees, Amazon PC DVG (Amazon PC Digital Video Games) and other digital PC stores back in the day - but none of those really got the traction the Steam deals thread did. And it was mostly, the same crew posting in all of these threads; yeah, across numerous threads.
So, the idea was to combine them all into one big thread. Steam Deals by far got the most buzz and traction...so hence, the evolution of the thread, becoming "Steam+" (Steam-Plus); meaning Steam plus any other digital stores.
I forgot who it was that came up w/ the idea or of it was a community-decided thing? Anyone remember and/or want to clarify?
Anyways...Our Humble, Fanatical, GOG Threads still gets decent amounts of traction, so those still have their own threads. Humble gets the most probably, other than the Steam+ deals thread.
Though, I do like Fanatical and GOG myself...so, I tend to make a fair amount of posts in those threads still and keep them alive. Others do post here & there and post deals there too, as those places still have solid deals.
