As a former PC-only gamer I don't think in generations but in years or decades.
Late 80s to late 90s
(MicroProse, Lucasfilm Games/LucasArts, Sierra On-Line, Dynamix, Westwood, Bullfrog, Interplay, Sir-tech, SSI, New World Computing, Access, Ensemble Studios, Blizzard, Bioware, Black Isle, Maxis, Origin Systems, Looking Glass, Ion Storm, Blue Byte, Ascaron, Psygnosis, DMA Design, Infogrames, Delphine, Acclaim, Accolade, Parallax, Spectrum Holobyte, id, Valve, Apogee/3D Realms, Epic [Mega]games and EA)
The golden age of RTS, TBS, point&click adventures and building, economic, flight and space sims.
The heyday, downfall and resurrection of western RPG.
Also of course the rise of FPS - unfortunately.
