So I started playing video games when I was pretty young and NES just came out, but opted for the sega genesis over the Super NES when the time came to upgrade. I found this game and after starting it I was hooked immediately. I struggled at first to understand the system in combat (or even RPG's in general, this was my first one), but the system is pretty simple. Each unit possesses a movement speed, affected by terrain, and then you can attack, use an item, end your turn, or magic. The story isn't exactly the most innovative, the traditional ancient evil, one group will push back the darkness, the fabled "Shining Force" as you are a light in the darkness. There are some cool units, the centaurs are fun, I really liked the mages myself and the ninja. Now, one of my favorite things was that once your units reached level 10 they could be upgraded to a new class, so the knight becomes a paladin, but it was also a balancing act as the longer you waited to promote the unit the stronger they were (you could wait up to level 20).
Now, my personal favorite of the group is Shining Force II, I have played that one through from start to finish at least 3 or 4 times. The story is much more engaging than the first, the animations are stronger, and there's a ton of really interesting areas. I really like the one zone where you're shrank. I'll leave it at that, but I was actually going to be running a D&D game based on it (oddly I just thought of it two nights ago)
I enjoyed the tactical combat of the series, it was decently difficult (at least I remember it that way), and the story was pretty good. I may have to DL it onthe VC for the Wii
