Both involve battles in space/land with high tech equipments
They both have basically 2 sides that is going against each-other and in both they have the protagonist be the winning chance to beat the "Dominant" side.
In heroic age, the main character has the ability to transform into something called the 'nodus' which is basically a giant armored fighting beast. While in Tytania the mc uses Strategy and tactics
If you enjoy space battles and the weak beating the strong with the help of the protagonist you will enjoy both of these anime's.
