Summary: The expansion does feel like it brings variety to the new game, without overkill. My wife and I haven't played the 6 to 7-player variant yet, but the duet version is how we play since getting the expansion. The new birds are beautifully painted, and the abilities are intriguing. I would recommend buying it! In-depth: My wife and I have been playing Wingspan about 2-3 times a week for the past 3 months. For Valentine's day, we decided to get an expansion to spice up the game. One of the aspects we enjoy about Wingspan is how many different ways there are to play the game, and no game is the same due to the variety of birds and ways to score points. The expansion definitely helped out in this way! We chose Asia over Europe or Oceania because there's a new duet game mode and a 6 or 7-player "flock" variant. Along with that, the bird cards seemed interesting and there were blue and yellow abilities as well! We haven't had the opportunity to play the flock variant yet, but we look forward to it! The main gist is there are two game boards set up with 2 people simultaneously playing at the same time from those different game boards. Pink powers become quite powerful because more people are participating, but you can't activate them with the player you're sharing a turn with. The duet version has been a fun addition because it adds another way of scoring points, adds a variety of new goals, and has the potential to grant a bonus for playing a bird. My wife and I started by playing with just the Asia birds for the first 6 games to get a feel of how to use the new abilities, trying to get exposed to the new goals, the change in strategy and playing style, and rules for each interaction. We enjoyed the games but were concerned that combining the 90 birds with the base game might make the Asia birds too powerful, and they would always be chosen over the original birds. We have since played 8 games with the combined deck and are happy to report that just like a good dinner, the Asia birds added enough spice to make the game more exciting, but we don't feel the birds are so overwhelming that they're the only ones played or that's all you can taste. Each decision is weighed upon for the best strategy, and sometimes if you can score points in three different ways with an original bird compared to one way with the Asia bird, then you'll still choose the base game bird! If you enjoy Wingspan, I'm sure you'll enjoy adding the Asian expansion to your collection!
