Well stopforumspam.org is down for maintenance and I am in a good mood today, even if the likelihood of spam from India is over 90 %.
So I will answer but remember that if you come back here and edit some "must buy" links in your signature you will be out of here faster than you can spell Kali.

Linux is good for some Valve games and Valves Steambox is actually 100% Linux.

Games like
Team Fortress do play perfectly on Linux. Team Fortress is Free but you can spend money in the store to get cool hats and weapons etc.
Linux is the preffered platform for the biggest game producer in the world so it will grow in importance.
Windows does still have the capability to play a lot of games - and probably more than Linux can at this point. But the trend is that those High end games are played with consoles like Xbox. Playstation and Steambox so the PC will take care of more Low end games (often with a better plot but less graphics).
So Linux is good for gaming and networking - so is Windows. In my experience Linux is better and securer on networking and I truly dislike the Samba protocol.
In the old days many would say that Windows was easier to use - but that is not the case anymore. So I guess it is a draw,
