Almost nothing here beyond the most generic ideas and vague sketches. Feels like filler churned out to meet a deadline. All you are buying is background lore for a bunch of jokey half-serious interstellar brands, most of which are very much tied to real Earth lore in various ways - burgers, golf, etc. There is no real indication that any of this was actually made up for a game or would be useful in a game, and really a list of brandnames and franchises with no details probably would have been as useful. If you are looking for something like, "How to spice up time portside" this is not it. I'm not even sure this is all that useful for "There is a meeting portside and you want to have some background color with respect to where that meeting takes place."

Would have felt I paid to much at $1. But at least it is a professional product.

Pros: useful, makes you think, unique naval/space take on familiar concepts.

Cons: $6 for 15 useful pages, some entries bland.

To give some background for the review: I read "Referee's Briefing 3: Going Portside" in one day on my tablet, and it is still fresh in my memory. I got it because I was looking for a pdf-only supplement for Mongoose Traveller 2E (New Traveller) while I am waiting for a discount on some physical books I want to get. My experience with Traveller is limited to the New Traveller: I have read the Starter Set, Companion, and High Guard so far.

This supplement promises "a miscellany of things to do and places to visit that are both interesting and memorable." That it does. Most entries either make you think about common pastimes in unusual (space/naval) context, or give you interesting bits of lore that make the locations come alive, or give the Referee little hooks on which to hang their adventures. The last one is a far fetch from full-blown adventure seeds, but it helps the Referee to start thinking.

With that said, some entries are just bland. One entry even tries to turn the blandness into a joke, but I would say it is not very successful at that. However, dull entries are in the minority.

The supplement consists of four chapters:

1. PORTSIDE FEATURES. This chapter gives you an overview of what to expect in a spaceport and makes you think about its environment and surroundings. It also has stats for a robot, which most likely require the rules from Central Supply Catalogue.
2. HOTELS, BARS AND RESTAURANTS. This chapter gives you a brief explanation of the role of these establishments in a Traveller's life and a list of nine entries. In my opinion, the forte of this chapter is not in the list of brands to drop into your game, but the background lore they tell you, such as naval-themed drinks.
3. RETAILERS, MERCHANTS AND SERVICE PROVIDERS. This chapter humanizes the "shopping interface" of the game. This may be helpful for a referee who wants to spend more table time on, well, shopping. The chapter also has a couple of vendors who look more like plot hooks and a little bit of background lore. Personally, I do not think it is great as the plot hooks are underdeveloped and the lore does not quite feel right, but it is subjective. The chapter is still pretty robust.
4. RECREATIONAL FACILITIES AND PLACES TO VISIT. This chapter made me go "neat, why didn't I think of that" a couple of times. Most of the locations (in a fairly broad sense) in this chapter can serve as unique backdrops for various missions. Some sites are a bit too vague or not as readily usable, but overall this chapter is excellent.

Overall, an entertaining read with a lot of neat ideas. I would recommend it even if you think that you can come up with various locations and things to do on your own. This supplement is more than a list of those things - it jogs the creative machine quite a bit and makes you think. If anyone has any questions about this review or the supplement though, leave a comment in the discussions tab, and I will try to respond.
