How exactly do you beta test then?
If not by playing the game?
Should I spend 2 hours walking against a random tree to make sure I don't glitch through?
Then move to the next tree?
How exactly do you go looking for bugs if not through simply playing the game to it's full extent?
This is all companies require of their beta testers anyway, play the game and report any bugs.
The savvy game dev sets up a hidden forum on their website visible only to beta testers with a bug report section.
People love that "exclusivity" and will congregate in the beta forum and talk about the game they're testing.
That's all beta testers are being asked to do.
I think you're jelly is all.
