I noticed this review for Relicta on gog's game page:

The best puzzle game since Talos Principle in my opinion.

Hey, I don't want to visit your site. Either give me the full review or none at all please. Has this become a thing here? I'm surprised this is even allowed.

I haven't checked what the rules say but where it asks you whether the review was useful, you can answer "no" and press report. I agree that people shouldn't be trying to lure users to external sites to read their reviews. (That said, GOG could make the reviews a lot more useful with a few changes.. another thing on a long list of things GOG can't be bothered with, and until then I understand why people might not want to post their reviews here)

You don't even need to own the game to review it on GOG. You can post anything on any game, absolutely useless.

With a limit of 2000 characters per review, it's impossible to put any proper full review on GOG. Assuming that is a link to a proper review and not some spam, of course. Was thinking of doing that myself a number of times, seeing as when I sit down to write a serious review I end up with more words than the number of characters GOG allows, way more in recent years, but just gave up on the idea.

Yeah, the 2000 character limit is.. well... truly limiting when it comes to writing reviews on GOG. Either way, it was a terrible move when they implemented it so no wonder some people are linking full reviews.

2000 char limit + no way to edit review = no desire whatsoever to write any reviews
