I wonder why so many people want to be testing nowadays ? This started around the turn of the millennium ... And since then, the pleas of people to allow some beta testing have - in tendency - rather become louder than quieter ...
I don't understand wh people are so much keen on testing ? I really don't know.
Okay, it *can* be fun, but it is mostly work, imho.
You need to have your eyes open all of the time.
I have been testing games for quite some time now. In my experience, when a company really listens to their testers and has a productive alpha/beta, the game usually comes out much more polished and bug free. People who are really passionate about a certain game (or game series) want to help in any way they can. This is usually in the form of testing.
Without a good alpha/beta, you end up with a game like Dungeon Siege 3 that failed completely. 20 minutes of multiplayer testing would have resulted in them knowing their system was garbage for PC players. But, you live and (hopefully) learn.
