Microsoft visual c++ in games

[Blueface]

Well ,as you maybe know,some games install that thing when you install them

I see i have installed the 2005,2008,2010 ,2012,2014 and 2015

I installed a Game just to open It (uhh spring cleaning task),not for playing It(the Game is called Kathy rain) and that Game installed me Microsoft visual 2005

Will something bad happen if i uninstall Microsoft visual c++ 2005 (only 2005)?

I also wonder why some games need that installed and some not

If nothing needs that particular redist then it is save to uninstall. However they are small (2005 is like 3 Mb) and not worth bothering with, just keep it around.

In general, it won't hurt at all to leave any redistributables like that installed.

The reason some games may require a particular older version of a redistributable, is that, particularly with older games where there were limited resources to work with, coding could rely on particular quirks in a set of libraries in order to function. Later updates could change those quirks, so requiring a particular version that you know is compatible became common.

Although rare, it was also possible that particular functions or libraries could be removed from later versions without consideration of backwards compatibility. If you've ever started up a really old game and got a missing dll error, it's likely due to this, where that dll is no longer installed by default on modern versions of the OS.
