XCOM2 is one of those games that i will play for years. XCOM was a great game and the second part improves on pretty much everything. The mod support is a huge plus as well, hopefully other game companies will go ahead and copy the approach of giving the players an SDK to play with.
XCOM2 is one of my Top5 all-time favorite games - recommended for everyone who likes a bit of a challenge and doesn't get frustrated easily. The only reason i don't have more playtime with this game is that i am currently spend most of my time in the SDK, making the A Better ADVENT mod.
