Which is my point. You hire (or like get volunteers for) early beta testers because they're the guys who are going to go around walking into walls looking for clipping errors. When you release an open beta, you do so with the knowledge that the people downloading it are doing so with the intent of playing the game, not looking for glitches, though they should be encouraged to report glitches if they find them. When you have a game as obviously incomplete as this (I haven't personally downloaded it), especially if it's just a simulator of another game, an open beta's not going to give you the feedback you want/need, or rather, it might, but it will be mixed in with "WTF WHERE IS STEALTH ROCK????"
