SHINING FORCE / Sega / Genesis
Hmm ... they did a Gameboy Advance remake of this that I thought was a small improvement (some dubious artwork aside), and added some new characters/maps/features, so if you have the means you may want to go that route instead.
This is a very good strategy-RPG, one of the grandpappies of the genre and deserving of its place in history.
Yeah, it's pretty simple as compared to today's strategy games, but still good fun. Good maps, good tunes, good graphics, good gameplay.
If you're limited on the Wii points, Shining Force 2 is a little better. Whatever route you choose though, this one is definitely worth playing at some point. A classic.
