The Fire Emblem Wii thread is on page 1 or 2 of discusssion
It's still the same FE game. Unit tactics battle, where you keep the units and level up each map. If a unit is defeated it is "gone forever" from your army. Requires some pretty good tactical thinking.
This pretty continues the story of the GC version (3 years later...). But it's a new story, you wont need to play the GC to understand. Laquz (shapechanges) are still there, but not quite as useless as last time.
It's very hard. I've done the 2 GBA and the GC version (Normal on all) and Normal on this had my failing on Chapter 1. I got to chapter 3 before it got too annoying. Far too much "1 hitting" by enemies.
Restarted on Easy - it's a bit too easy tbh (up to chapter 6). Hopefully it gets bit harder later on.
