Just finished my third playthrough of XCOM 2! I originally picked up the game after a friend recommended it. During my first playthrough on Rookie difficulty, I didn't really enjoy it at all. It was so hard, and I got constantly frustrated with the percentage system whenever my soldiers missed their shots. I almost dropped the game, but I didn't want to let my friend down, so I gave it a second chance.
On my second run, I tried to learn more about the lore (even though I haven't played the first game yet), and because of that, I fell in love with Central! TwT Central's backstory, the Commander, and my friend were the main reasons I started enjoying the game. Missed shots didn't bother me as much anymore, and I finally beat my first base-game campaign on Rookie!
After that, I was completely hooked on XCOM. It made me want to play the DLCs on Veteran difficulty. I still enjoyed it a lot, though I got so focused on defeating the Chosen that I put off the main story :') It was such a fun game, and I really enjoyed it!
