This relates to Fire Emblem series and the consoles they were released on respectively.
A strange pattern...
FE1: Dark Dragon, Sword of Light (NES)
FE2: Gaiden (NES)
---
FE3: Mystery (SNES)
FE4: Holy War (SNES)
FE5: 776 (SNES)
---
FE6: Sword of Seals (GBA)
FE7: Blazing Sword (GBA)
FE8: Sacred Stones (GBA)
---
FE9: Path of Radiance (GC) [Console]
FE10: Radiant Dawn (Wii) [Console]
---
FE11: Shadow Dragon (DS)
FE12: New Mystery (DS)
FE13: (3DS)
Two NES games, three SNES games, three GBA games, two console games, and now three DS games.
It seems the pattern is 2, 3, 3, 2, 3... I wonder what consoles the next three FE's will be released on?
