Too many mix-ups with Win9x era and runnable games here.
Limiting games to Windows XP (usually Windows 2000 also included - the so called NT5+ group) as the minimum required OS in the System Requirements will be more appropriate for this thread title.
I don't think it's that clear cut. Some people used Win9x until 2005, while others upgraded to Win2K/XP as soon as those became available. So defining when one era ends and another begins tends to be subjective. Furthermore, most games didn't actually start requiring Win2K/XP (i.e. can't be installed under Win9x) until 2004-2005.
On the other hand, a lot of games released in 2002 and onward will run better when using a newer, more powerful CPU/GPU. Meaning, a system that doesn't have Win9x drivers, and therefore needs WinXP. Heck, even some late 2000 and 2001 titles will deliver superior performance in that scenario, because they were poorly optimized, and didn't run well on period-correct hardware.
Of course, this applies if one wants to play games at high resolutions, with AA/AF, while maintaining a locked 60 FPS. But if that level of performance is not desired, then Win9x running on less powerful hardware can be used for games from the early-mid 2000s.
