answer:I have played Rekka no Ken, Sacred Stones, and Awakening. It is more or less similar in each game, but far less intuitive in the older games. In order to increase the support of the characters, they must fight adjacent to each other. If you are trying to gain support for two characters, they should stick to fighting side by side consistently. I’m not positive, but I think in the older games, trying to gain multiple supports per character does not work. You want to pick one path for them and stick to it (such as only supporting Lyn with Eliwood in Rekka no Ken.) In my experience, certain characters are easier to pair off and gain support with, too. Fire Emblem: Awakening provides some tutorial help for the support system and enables you to support characters with multiple people (though certain characters are limited.) In general, Awakening is more intuitive than the past games and it is a massive game with a decent DLC library. I highly recommend it to fans of the series.
