I held off on bringing this up because I thought the appropriate people on GOG would have been on top of the issue, but nothing has happened so I wanted to see if the issue was only on my end. (I mentioned it once in one of the stickied threads and Judas told me to contact support, but I was hoping they would have already noticed the issue.)

I believe no game released since The Journeyman Project: Pegasus Prime has any "avg. user rating" visible and only 3 reviews viewable. Does anyone else have this issue or does it somehow have something to do with my version of Firefox?

Nope, you're not the only one. Aside from Moebius, all other games show no average rating, nor more than 3 reviews, regardless of browser.

There's supposed to be at least 5 reviews for The Samaritan Paradox but only 3 are showing up. I'm not drunk or imaging this because I wrote a review myself and it appears to be not appearing. How are we supposed to promote good games if the reviews aren't showing up, some people might be more reluctant to make a purchase if there are too few reviews and no ratings.

PS: Hope you're enjoying the game, have you finished it already?

Well, I installed it and started playing it. Got stuck almost at the beginning (at the point where I had to find what the isbn code meant) but finally, I hadn't seen the newspaper on the table, and after that proceded normally. :-D Now I'm at the mansion of the writers daughter, made her mother hear the music record, but couldn't figure out how I should turn the horse statuette on the pedestal to see whatever the writer had hidden. Thankfully, I won't have to bother you however with my getting stuck like every 10 minutes (I like adventure games,it's just that I need walkthroughs for the most difficult of them), as I found a video walkthrough on youtube and I'm going to follow that one when I get stuck. For the moment however, I'm not going to progress much further than that, as I'm going to have my university exams in a week and got to study...

P.S. Excepting the above, I'm enjoying the game very much-liked the plot for example, and this is a basic tenet of my enjoyment in games !

As I told you earlier on, you can ask me about the game at any time but it's great to hear there are now walkthroughs and whatnot available. Guess I got lucky not getting stuck with this one or maybe I somehow think similarly to the creator of the game because I usually get stuck in almost every adventure game, even though I've been playing those for 25 years. Even in the easier ones, I can get stuck in some place.
When I was in school, I used to call up my buddy from whom I borrowed some of the early LucasArts titles. One time, I got so excited about the game I was playing that I called him again a mere 10 minutes later because I got stuck, yet again. So I have patience nowadays when other people get stuck, believe me!

Any blue comment on the issue? :-)

Seems to have been fixed. All games with the exception of Pinball World have both an average rating and more than 3 reviews.

Yup, it has been fixed now. Thanks!
