I'm less relevant around here, but I'm keeping with my tradition of trading lifetime Fooldom Come subscriptions for lone games off my Steam wishlist. Fooldom Come is a passport to my games such as Flesh And Drone, Fused Finale, Gears & Peers, MeanderGall, PathWrath 2, Wrangle, Warp And Weep and more.
Details are included in the passport's hub forum. Even if you're not interested in Fooldom Come, it might serve as a handy list of cheap game recommendations.
Fooldom Come is not a game or developer resource. It therefore doesn't get automatically included in the main forums and I'm guessing this doesn't qualify as an event. Apologies if this is now considered spam. Either way, general steam sale discussion is welcome.
Here's the hub forum post again.
