I’m splitting hairs, here, but I have to take exception to your comparison of Lost Planet: Extreme Condition to Starship Troopers’ novel version. While Starship Troopers’ effects on the Real Robot genre cannot be denied, the mecha in Lost Planet are very dissimilar to the novel’s powered armor, which were extremely mobile through the use of long jumps powered by thrusters, and were capable of controlling square miles of territory through sheer firepower. The mecha of Lost Planet are more limited in their firepower and movement, which is fitting given their invention in-canon is based on space construction suits (somewhat like Mobile Suit Gundam’s mythos, really).

Mobile Suit Gundam’s mecha are probably a bit closer to the mecha of Starship Troopers, as we can see the Gundam “flying” through jumping and the application of thrusters over large amounts of territory, an ability that even makes its way into the name of the OP’s theme song, “Tobe Gundam” (“Fly, Gundam”).

The Akrid are also a lot closer to the Bugs of the Starship Troopers movie than they are to the Bugs of the novel. While the Akrid definitely do have the subterranean aspects of the novel version’s Bugs, the Bugs of the novel are definitely an intelligent, technological species, while the Akrid are more like (very cool looking) giant monsters.

(For those of you confused by the above, the novel version of Starship Troopers is very different from the movie version, and the titular Troopers in the novel wear powered armor, often equipped with limited-power nuclear weapons and jets capable of “bouncing” over miles of territory, rather than being the cannon fodder of Starship Troopers’ movie. Supposedly, the movie was actually called something else entirely before someone noticed a similarity between some aspects of the proposed movie and novel.)
