Azur Lane is the only game that I regularly return to play after all these years, The game production is top level, they also made it into its own anime. the game has it all, chat system, guild system to stay close to your friends, a huge roster of the most beautiful characters, insanely good looking graphics, fantastic music, exciting story lines.
But most importantly azure lane is the most gacha friendly game of all. You get daily pulls for free every day. And it's so easy to accumulate pull currency.
All in all it offers a great game experience. Daily game can be very fast or very long if you re a completionist, the game has so may modes it offers something for everyone.
On the minor negative things It's gameplay can feel old styled, grindy and repetitive at times but there is repeat and auto fight mode if you don't wish to play manually, so it's OK. Also they introduce too many difficult to understand game modes and meta characters in game systems that are difficult to obtain. They still make new events every three weeks with so much content, each time introducing new stories, new mini games and characters and costumes. I only wish they lasted longer and they were easier to complete. Sometimes they repeat events but this should have happened more frequently.
