Lets see - main plot structures to NGE off the top of my head
- There are only three gigantic robots left - called Evas
- The gigantic robots are built to fight the invading monsters (called Angels)
- It is very hard to find pilots/people in the whole world who can drive the robots in that they can form the necessary telepathic link to control the robot
- The monsters (Angels) are organic and come in successive waves getting bigger and nastier as they go
- The monsters abruptly appear through some sort of inter-dimensional portal
- The Robots are all stationed together as one last defence to defend one large Asian city
- In addition to the elite pilots who drive the Robots there is a huge military base full of maintenance and IT people who are also simultaneously assisting with the control and drive of the robots
- There are all sort of dramas amongst the different robot pilots
Now - if you substitute the word 'Eva' from NGE for 'Jaeger' and 'Angel' from NGE for 'Kenju' (I think thats the term) you essentially have Pacific Rim
