if you count a user base of 4-5% a competition then every other launcher is a competition to steam, which i completely disagree with. 4-5% isnt even barely a competition, its a couple of people deviating from the norm.

and to the network effeft:

...depends on the number of users of compatible products

what exactly has to be compatible here? the game will run no matter where i buy it, the only difference is how enjoyable the launcher is
