All of this looks pretty boss. It is unfortunate that they don't include two monsters I've been wanting to fight for awhile: Akura Jebia and Akura Vashimu.
Monsters exclusive to Frontier are unlikely to ever be brought over to other games (at least not for a looooong time). IIRC, a different team works on Frontier, and that includes monster designs. Frontier-exclusive monsters have a different flair and style than most other monsters in the series. Perhaps 4 will give us a different scorpion-like monster.
Dark areas were probably removed because they were quite annoying, and let's face it: how many people just turned up the brightness on their TV? --- lee-oh-leh-ee-ah. It is perfectly okay to write garbage--as long as you edit brilliantly. --Carolyn Janice Cherryh
