I first started out as a Human but now I mainly play as an Elf. Linthradil and the other Elven girls truly swayed me to their side. Though I miss my old Reich days. Elintor and Geldar have fun rosters that make going elf worth it.
Funny thing about the Giants however, they use the voices and models from the Warhammer "Grim Age Ostland Campaign" mod which was sadly never finished, but there is a demo out in case you want to see. Of course they're used in Warsword Conquest too.
