If you look at the history of game developers, it is easy to notice that many tier 1 companies experienced what you could describe as a golden decade and after that turned into mediocre companies milking their past successes. Examples:
Blizzard - the first largely successful game was WarCraft 2 (1995). After that everything that Blizzard built turned into gold, until the success of WoW (2004) and its early expansions. Blizzard started to decline rapidly with the releases of WotLK and Catalysm. I do not think I need to comment on the current state of affairs.
id Software - Wolfesntein 3D (1992) put them on the radar and Doom (1993) elevated them to the status of masters of the FPS genre (no pun intended). Quake series was also great. The last successful release from id was Doom 3 (2004), which sold well, though it was not universally praised at that time (I personally enjoyed that game). Rage was a disappointment and next Doom was in development hell for almost a decade, resulting in the company being sold.
Raven Software - once subcontractors of id Software, releasing clones of their games, they gained recognition with Heretic released in 1995. This was followed by a series of successful games, with RtCW being a highlight. Quake 4 in 2005 was a disapoointment, which, combined with failure of Wolfenstein 2009 resulted in Activision relegating Raven to the status of a DLC shop.
BioWare - BG was a smash hit in 1998, followed by great-to-decent releases. The last good old-school BioWare game is arguably DAO released in 2009.
Why do you think it happens? Do devs burn out after a decade or do owners of successful companies want to cash out as soon as possible?
