Mobile Suit Gundam SEED, Mobile Suit Gundam 00 Recommendations
The anime which led me to this one. It's a very hard decision for me to choose which Gundam series I enjoyed more so... why not both? I reccomend Gundam SEED if you liked 00, because they're quite similar in the fact that the art, characters, music, and story were both on the "god-like" level. Ingenious.... masterpiece... Finding words to praise both these anime is really quite difficult XD
Both the shows features awesome mechs and pilots with a strong story revolving around some form of conflict.
In Gundam 00 it's about Celestial Being against the world trying to bring an end to war through armed interventions. Whereas Gundam Seed pits Naturals against the Coordinators where both sides are trying to reign as the dominate sub-species of humanity.
Although both shows execute their stories differently, ultimately they both aim for the same goal 'the end of war as a whole'.
So if you're looking for something similar to Gundam 00, then Gundam Seed is one of your closest bets for experiencing it. And as an end note
