It works fine on a technical level but it's just not fun. The gameplay is very minimalistic unlike the actual Fire Emblem games, the story is garbage, the meta is an absolute mess. It's also pay to win considering to beat the harder content you need to get the rare heroes several times over to level them up and has a subscription that paywalls a lot of content. It also has absolutely terrible powercreep. All in all playing this game feels more like an obligation than something I look forward to.
