One could argue that making a video game that gets a lot of good reviews is a sign of a potentially good game developer.
That’s of course assuming the reviews are legitimate, which is what OP is trying to achieve.
I agree- but, my issue is- if someon posts a game, and knows the criteria for success is to get as many five star reviews as possible, then the natural progression is that they'll try to get all their friends, all their family, all their work colleagues, anyone who owes them a favour etc. etc. to give them a five star review- regardless of whether they've even played the game.
Essentially, it becomes a popularity contest, like Americans selling cookies on behalf of their children, and the quality and effort put into the game becomes completely irrelevant.
Fair enough. I've got to say, I have a lot of questions I'd like to put to the OP but... nevermind- not my problem ;)
Slight Edit: I'm thinking if the OP thinks that checking IP addresses will be enough to stop fake reviews then... maybe not? I mean, we've had some weird reviews from some interesting people but never anyone just saying "great game" or "fantastic game" on the only game they've ever reviewed! Ok, I'll stop now, I promise ;)
