Tir na nOg: Blessings & Burdens ►►► Is this is a must have expansion? (and is it a must have game?)

About Tír na nÓg: Blessings & Burdens, from BoardGameGeek:

Tír na nÓg: Blessings & Burdens expands your journey into the Otherworld with five powerful new modules. Mix and match them however you wish-each brings fresh twists, daring choices, and unexpected challenges. Every module reshapes setup, rules, and scoring, and several include solo play so you can test your fate alone. Module 1 – New Geas Cards New destinies await! Six fresh Geas cards (two per Saga row) open up bold new paths. Use them on their own, combine them with the base set, or dare to play asymmetrically with different cards for each player-if you're ready, the Morrigan herself awaits you in Module 5. Module 2 – Blessed Realms What will you sacrifice? Each card you discard sways the fate of the Realms, shifting their value for endgame scoring. Do you burn a color to make a region thrive-or keep it to build your own legend? Module 3 – The Lore of Places Rise as a Mormaer, a ruler of regions. Claim dominance in a color to unlock special once-per-round powers and bend the story of your Saga to your will. Module 4 – Triquetra Honor the sacred unity of all things! Complete Triquetra goals to claim blessings-divine gifts that let you change a card's rank, swap cards in your Saga, or even place a Bridge, a mystical new tool that bends space to connect cards diagonally or across gaps. Every player who reaches the goal that round is blessed, but only the swiftest earns the glory of being first. Module 5 – Followers of the Morrigan (2+ players) The Morrigan whispers… Draft and command your own unique set of Geas cards, giving each player a singular fate. You were going to try it anyway-now the rules of chaos have been written.
