I will answer your question Wotto by saying this.
Heres an example I will use as a reference.
A member buys a brand new pinball machine, spends his hard earnt $6500 or $9500 etc. The member is proud of his new purchase, proud he worked his arse out to buy it. He takes photos, places some posts on the forum and is excited with his new purchase. Most members say nice things about the machine, and as members learn more n more about the machine, or see more videos etc, they politely say they like it alot etc etc. Over a 2 or 10 day discussion, certain members might say different nice things about the game, because they like different parts of the game etc etc etc, and you ofcourse, as the proud new owner, likes the feedback that the members give you, as any new proud owner would.
THEN you have 1 or 2 members who rubbish your game so to speak, call it various names, tell u that u only bought it cause u were pressured into it by others, and basically they just rubbish the game badly. Then after that, 3 or 4 members say they like it, but then the same member bags the shit out of your game again and again and again. I am sure you would get sick of that soon after and feel that is negative and unwanted negative feedback, because you have already heard that from the same person over and over again.
So thats why i say or believe it is nice to get positive feedback once or more, but it serves no purpose to hear someone repeatedly bag your new game. It would become/may become inappropriate after a while I would think.
The way to put this into perspective, is to think about a machine you just bought and how you would feel if the same person/persons repeatedly bagged it over n over again. Once u hear the opinion, there no need to hear the not so nice one over and over again.
That way, people who do spend their hard earnt $$ on a new title, dont have to have their proud moment of unveiling on the forum bagged to death etc. It was something i felt would keep this place fun and show some politeness to other members. Thats all.
