Shining Force is basically Sega's take on Fire Emblem and borrows a lot of elements from it. However, it also adds and changes enough elements to feel unique. The most noticeable differences are two. First, Shining Force's progression is through exploring, like you would in regular RPGs. Second, the turn system is based on character speed rather than fixed "Player Phase" and "Enemy Phase". Essentially, faster characters go first so turns will constantly change between you and the enemy. There's many other small differences, like how counterattacks and double attacks are handled, but those two are the main ones IMO.

Overall, I really liked the game. The turn system is a little unpredictable but if you're patient and smart about when to push forward you'll safely clear most battles, although some can be pretty difficult. If you're looking for a fun RPG I can definitely recommend this one!
