Romancing SaGa 2 has a unique concept and gameplay:

- You direct generations of rulers of an Empire oven the span of up to several millenia! Your goal is to gain support and lands in order to face Seven Heroes of old.
- Beside the very beginning and the very end of the adventure, your characters will change all the time - there is no 'main character' or 'main cast' - and the game is non-linear (you can do most quests in any order provided you can access them, be it in space or time).
- There are more than 30 character classes which you can't possibly all see in a single regular playthrough.

(Crowns) which is gained after each battle depending on the size of your Empire and the quests you have completed, and found in chests in the dungeons you explore.
- Enemy item drops are very rare. Mindless grinding in order to get them (or to get artificially stronger, for that matter) is not recommended, as enemies will become very strong fast.
- All of this means a unique gaming experience and a great replay value!
