1985 says hi again. Back during the mid- to late 1980s, PC games were experiencing rising costs with lowering returns, not a winning formula. They even introduced the closest thing to DRM that they could at the time, given the limits of the technology: password protection in games that required you to consult the manual regularly when playing a game and type in random stuff from said manual just to be able to continue playing. It got out of hand, to say the least, and game sales went downhill fast as the obsession with preventing piracy got stronger.
The solution, which took developers about 3 years to accept was a solution, was the NES. The underpowered TV-displayed computer that could "never ever" beat the Amiga or Commodore was beating them quite handily, and Nintendo was making money hand-over-fist on the gray box of doom. By 1988, developers were swarming to the NES, because it was insanity to keep making PC games when the PC games kept costing more and bringing in less. They were rewarded with marginally better sales, and far lower development costs.
Expect to see something very similar happen soon with the developers who are going to survive this cycle. Of course, the darling of the mainstream this time is the Wii, not the NES...
