I was sent a free copy of the Building Better Worlds expansion for the Alien Roleplaying Game to review for my blog. I haven’t had a chance to run the system yet, but I have read through the books. This will be my honest impressions. If you’re thinking of running Alien RPG at your table, you need to start with the core rulebook, Building Better Worlds is meant to be a supplement. I have detailed write-ups for the core rulebook and the Heart of Darkness module you should also check out.

The Book
Quality
Free League Publishing continues its streak of high-quality rulebooks with this beautifully printed expansion. While the pdf won’t be printer-friendly, fans new and old of the Alien franchise will appreciate the beautiful artwork that lines its pages. Even if you don’t like physical media, you might want to make an exception. Feeling the pages between your fingers, and smelling that new book smell makes the experience hit different. Don’t get me wrong, the PDF is enough, but if you have space on your shelf, the book is pretty sweet.
What is it?
Building Better Worlds is meant to be an aid for the Game Mother who needs it. The book includes:
- Rules for Colonization
- New Feats and Personal Agendas for existing classes
- Two new classes: Entertainer and Wildcatter
- New Weapons
- New Vehicles and Ships
- New Planets and Systems
- New Aliens to fear
- 7 Expeditions to run
- Lots of flavor and backstory.



If you need ideas on what to run, new creatures to fill your adventures, or gear for your players, you might want to look into this expansion. It is by no means a necessity, but it is a great resource.
Impressions
I didn’t have much interest in the Alien universe prior to picking up the RPG. It wasn’t until I started reading the lore and timeline that I decided that I needed a better understanding. I’ve started making my way through the novels and movies, and it’s given me a better appreciation for how much flavor and care is put into these books.

I appreciate that the book includes timelines of important dates because it makes it easier to keep track of everything that is going on. If you don’t know anything about the alien universe, you will before you run your session zero. The book does a great job of laying out the lore and history in a way that makes sense but also fits its dark sci-fi theme. It gets deep, and I would almost recommend it as reading material.
If you need something to spice up your next campaign, the monsters in this book are pretty spicy. There are some brutal creatures that can end an adventure. I don’t think my playgroup would care too much about the colony mechanics, but the expeditions seem fun and there are some vehicles and weapons I’m sure they’ll want to work towards.
If you’re looking for a brutal and unforgiving system to run at your table, you run Alien RPG. If you need ideas for your next campaign, Building Better Worlds seems like a nifty little expansion.
