There's a life cycle to PC gaming. It goes something like this.
Indie developers start tiny, hyper-innovative game titles on PC.
Indie title explodes. (see: Minecraft)
Indie dev starts making bigger, more polished PC exclusives.
Indie dev becomes multi-platform gaming juggernaut, or gets absorbed by one (bought out).
Juggernaut chases the money and eventually goes console-only.
Juggernaut dies a slow, pitiful death after abandoning its gaming roots.
Juggernaut dissolves, with many of the original team returning to their roots.
