"Yggdra Union is solid, and is designed to please its audience. Engaging characters and difficult battles, both full of twists, are sure to keep players ready to press on "just until I get through this next battlefield." The difficulty curve can be steep, and poorly planned attacks will certainly punish the player, but this serves to make wins that more rewarding. Card battle and strategy aficionados will definitely be thrilled with each victory. Action gamers and the impatient need not apply."
