My question might be a bit too novice, so please bear with me. I am building a game and I want to link the Achievements to a website of my own. Based on what I know, that would require establishing a linkage between Unity Client and Web Server(which I pay for). Further, I will need to hook up the Server to my Web App. I want to do this in as effortless manner as possible. I will most likely have several leaderboards, achievement trackers.
What I don't want is to have Steam or any other distribution service in the stack. I am not very knowledgeable in this regard, so could you direct me as to what I should do and how I should go about. To put it simply, I want the player to download the Unity game from my website, play it with internet connection and have their achievements directly sent to the Web server (which I will use for my website).
