Activation key for a game in beta/alpha

So later when i get my game in alpha/beta. I want it where players have to have a activation key to play the game. What would i need to do this?

just lock the file with a passkey activation

Is it going to be a commercial game? They have to pay to get the activation key?

It can be quite tough finding people to alpha and beta test. If you add an extra layer of needing a key this may make it more difficult still. Is there a reason that encryption wouldn't be enough?

I don't know it was just an idea ;) ty for answering tho and the game will most likely be commercial

If it's commercial and you want a demo, with an activation key to unlock the full version, you'll need DRM. IN that case, look at the pinned threads in the commercial area forum.


If it's not commercial, I really wouldn't bother with an activation key - if they don't have to do anything (like pay for the game) to receive it, then you're just putting up an unnecessary barrier for them.
