Honestly. the STEAM.an ultimate location where you want to spend all your time in. all the latest games available at your fingertips.super cool stuff happens a lot of time, you can expect some good perks.like common man. people trade stuff and earn money.apart from that. you get the latest deals and up to date information and version of games.no waiting.even a little kid can understand how to operate the website.
very short period of maintenance.if you ever encountered them though.
you get a very personalized never ending list of games based on your past activity, your interests, what your friends play.and in that what your friends actually like.steam sometimes gives you some perks like discount trading cards which you can use for discounts or gift them to your friend!
one heck of a world to be in.100% of the gamer are originated from steam.myself. I put my 900+ hours in Counter strike global offensive game. and it has just been 1 year since I bought that game.
all credits to this steam which lead me to be a dank gamer.which I can proudly say of.and yes. I do sometimes play coc for time-pass when there is no better ping/ wifi.:P
