While Fire Emblem Engage adds a few new features to the franchise formula, it's really a fairly traditional Fire Emblem experience in many ways. Among other things, the game also has a huge cast of players you can recruit to join your party.
The problem with that feature is already causing worry among Fire Emblem enthusiasts. After all, what's worse (relatively speaking) than the notion that you could have added a powerful new character to your party but missed the opportunity? The good news is that most of the game's characters are automatically added to your roster when you reach certain milestones in the main campaign.
If you're worried about missing a particular character (or you're just wanting to "collect them all"), here's a hopefully helpful guide on how to recruit every character in Fire Emblem Engage.
