In Issue 5 of Perfidious Albion, Charles Vasey and Geoff Barnard traded comments about the game. Barnard noted, "The game seemed quite interesting to receive and study, although the physical quality is not the best. However, playing the game revealed some problems in play-interest. For example, once the ground forces are landed, the space combat which should continue is pointless! ... an interesting system, especially if you have read [The People of the Wind]." Vasey replied, "It certainly is most important that one has read the book, as it certainly brings the otherwise boring maps to life ... I feel that most of the [problems with the combat system] are due to the 'primitive' system used." Barnard concluded "Not the best of games. It should be possible to put this right, maybe with altered victory condition." Vasey concluded, "This is not a game I really enjoyed ... for all this, it is one of the few games to simulate this kind of warfare in a reasonably realistic manner."[3]
In 1976, reviews appeared in four consecutive issues of The Space Gamer:
- In Issue 5, Rick Mataka gave a positive review, saying, "The Ythri is a game simulation I can recommend for any gamer. For the beginner this is a game that is easy to learn. For the Veteran it is a game that can be challenging."[4]
- In Issue 6, Norman Howe was also impressed, writing, "The Ythri is a fine game, with great potential. It's one of the few I've seen which provides sufficient numbers of spare counters to work with. This versatility definitely outweighs any problems with the basic scenario."[5]
- In Issue 7, Tim Hawkinson noted some issues, but concluded, "All in all, playability is good. As the rules note, it is a good idea to make a few alterations with the rules to suit your taste. But basically, The Ythri provides a good scenario, and Metagaming Concepts should be commended for another great game."[1]
- In Issue 8, William Brogen gave a positive review, saying, "This is an innovative and mind-stretching game with a lot to offer, both as the basic game and as a base to build on."[6]
In his 1977 book The Comprehensive Guide to Board Wargaming, Nicholas Palmer thought that only Poul Anderson fans would be interested, calling this game a "lively, simple simulation [...] mainly suitable for readers of [Anderson's novel]."[7]
