I’ve been trying out a lot of betas and even a few alphas recently.  Some have been very very good (Ghost Recon Wildlands for example) and some have been pretty darn bad (Steep).  The one thing that really makes or breaks it though is feedback and reporting mechanisms.  Let me give you an example of a current Beta I’m in, without naming names since I probably signed an NDA somewhere in clicking to install it. They were nice enough to send out a feedback forum link with the invitation. However, they used uservoice and it’s really hard to navigate and everything is classified as ‘ideas’ that people vote on.  Bugs and general feedback don’t fit this model well and makes it less likely people will post. However, because he Beta itself is so derisive, redoing something that worked well before into something unuseful, I put up with it and submitted stuff anyways.  Here’s hoping it makes it though the quagmire and they fix the glaring issues before going live.
