If you loved Enemy Unknown you'll love Enemy Within, if you didn't, it hasn't changed anything that's going to make you like it. This in combination with the accuracy estimates seeming to be being a little off or having a new hidden penalty, it can get frustrating, especially on classic or higher difficulty. My minor complaints are that the difficulty curve can be a bit wonky at the start, especially if you've played through the campaign multiple times already and move the story ahead too quickly, the scripted story missions will start throwing very difficult aliens at you way before you're adequately ready to handle them. Difficulty - Toss up overall, EW has a slight edge.

Shame really, the XCOM 2 psi-operatives and templars were better than psi-operatives in EU/EW. But they just couldn't make me feel as awesome as I did in EU/EW. I don't want to spoil the game for you by revealing too much, but If you beat EW, you will most likely not even think about going back to EU. XCOM 2 tried, especially in that scene where your soldiers saluted your Avatar as you went to the last mission.

It had more abilities, more synergies, and was generally more fun. EU and EW are very similar, but EW has extra stuff which makes it superior to EU. Tweaks to the meta-game like facility adjacency bonus' are also welcome. I feel like XCOM 2 is better game generally, but XCOM EU/EW has flavour which XCOM 2 lacks. The AI seems to have gotten a bit of an overhaul and uses high ground, supression, overwatch, flanking more effectively. It's a bit pricey, but if you shopped around you could have got it for a 20 dollar pre-order and i'm sure it'll be on sale over the holidays. It adds great gameplay features to an already great game, with all the features added the campaign will feel new even though it's the same.
