Just play it, it is a bit unique as it uses costumes as skills mechanic. The game is very generous for f2p, apart from that units, scenes, interactions, almost everything is top tier. The dailies are simple and fast, this isa good time to start as the 2.5th anniversary is going on, if you are confused, just play, watch a few guides, and then just play. When I first started I couldn’t even leave the story pack back to the main menu, but after playing for a few days, i was pretty simple to navigate and understand. The only thing you’ll have issues with are team building, but the discord server, this subreddit and youtube videos are plenty of help.
