Indeed. In the era of inexhaustible published gameplay, reviews are kinda superfluous.
You do not convince. If the users decide that a - from your point of view - useless review is indeed of use to them, then it is. The users decide what's up top.
And as I said previously, all this is sidestepped easily enough by merely using the introductory phrase "Good/bad game, but:".
This interference looks petty and that's pretty much its only effect.
No, what actually looks petty is someone leaving an off-topic review complaining that it was flagged as off-topic.
