Because I'm toying with the idea of designing an Aigis like game in the future, I wanted to break down what Aigis had going for it in gameplay design. Mainly because Aigis is less an H game and more a strategic tower defense game with an H feature.

I guess the first thing that really caught my attention about Aigis is that while premium units are strong, event units, depending on the unit, can be on par with some of the units from the summon gate. Most other gacha type games usually place all the power units in the gacha (I'm thinking back to when I used to play Brave Frontier, and events in that game were less about featured units for usage and more for featured units for acquisition).
