How does someone become a tester for future games such as Forza Horizon and Motorsport series? I always have suggestions or test things out on the game and was wondering how does one get a beta copy from devs to test.
Aside BETA’s I’m very interested in some kind of FORZA insider tester program as well.
Testing is a lot different. Not gonna go in depth but testing definitely does not work that way in the sense of you play game and gives devs suggestions.
I am going to be in Seattle in a week for vacation see my Daughter and Grandkids. I would gladly “drop by” and give this a test run for them 
It doesn’t work like that. Microsoft has their internal test team. You can apply for that and you might get to test some games, or you end up testing the Windows Explorer for the next twenty years. If you live in Seattle you might get chosen for a focus test group, but I don’t think Forza does that anymore. They know what to do.
In any case testing games is never like you expect it to be, playing the game. It’s about repeating steps the devs give you a bazillion times and writing them down. If you like to start a race and then quit the game, restart the console, do it 100 times again, writing down every time what happened, then go for it. But the truth is testing is the most boring job in the world, and it pays really really bad.
