Well, my browser decided to be slow, and I clicked comment twice, which posted my comment twice on a game. I found out then that we have no ability to delete our own comments on games, which kind of sucks.
Then we have the one time vote. I mean, it isn't set in stone when game magazines like Game Informer make a rating, even some show a second rating reconsidering things. We have changes in taste ourselves and we might find that we're interesting in certain genres that we weren't before and might of played a game in this new interest and seen we voted a four or something when now we see it as a 8, 9, or 10.
changing rates is a bad idea people! ulimitedpower said one reason ,the second is that some people like to look for games by RATINGS now someone gets used to some list ,and imagine how confused he will be ,he can maybe even report the games missing (MAYBE) IT WOULD COMPLICATE IT!! but the thing that we can erase our double posts isnt such bad ,the bad part is this:
Some post milions of comments ,comments just flooding in,and then he erases all the comments and leaves only ONE and the mods have no one to tell them if they were spamming ,and they weould have a LOOOOT of AP`s i must say :P
