There are four different current series/teams of tactical rpg's that are popular and that are released in the United States.

I'll list all tactical rpg's from each of the four teams/series, including ones not released in Usa...

1. Yasumi Matsuno/Ivalice/Ogre teams(s)
Ogre Battle, Tactics Ogre, Final Fantasy Tactics, Ogre Battle 64, Ogre Battle Gaiden, Tactics Ogre: The Knight of Lodis, Final Fantasy Tactics Advance, Final Fantasy XII: Revenant Wings, Final Fantasy Tactics A2

2. Nippon Ichi Software team
Disgaea, La Pucelle: Tactics, Phantom Brave, Makai Kingdom, Disgaea 2, Soul Nomad & the World Eaters, Disgaea 3

3. Front Mission team
Front Mission 1, Front Mission 2, Front Mission 3, Front Mission 4, Front Mission 5: Scars of the War

4. Fire Emblem team
many non-Usa games, Fire Emblem: Blazing Sword, Fire Emblem: The Sacred Stones, Fire Emblem: Path of Radiance, Fire Emblem: Radiant Dawn

My favorite team is the first team, which split up into two teams after Tactics Ogre but merged back into one team starting with Final Fantasy Tactics Advance. I love team 3 also! I haven't played any games by teams 2 and teams 4 but they seem interesting and I hope to play them.

What is your favorite team? My vote is for Team 1!! You may choose another team as long as they have atleast 2 Usa released tactical rpg's.
