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 only like testing IF it bring more quality to a game since more people give their comments etc ... can improve the quality, maybe give the developers new ideas to include etc etc ...
For me testing = working ! It's a serious quest to do and require/demand the full investment of all my abilities to be a valuable tester to which the dev's have something to !
Indeed, eyes wide open !

Only if they ask to "mark" the quality to the sound tracks I close my eyes and listen !

But I have full confidence in Kirill Prokovsky's abilities to make again beautifull sounds ... !
