Fan Nickname: Because the otherFinal Boss of the first game has no officially given name, fans refer to its first form as either "Squid" due to its squid-like appearance or "NoName". The latter could also be applied to its Rounder-like second form.
No Export for You: While the first game averts this thanks to UbiSoft, the downloadable contents of the first game that consists of extra costumes for each character in the game were never released outside of Japan. However, if one manages create a Japanese Xbox LIVE account and import the Japanese Microsoft Points, the DLC costumes can be purchased and used in North American and European versions of the game since they're region-free.
The game's sequel, Senko no Ronde: Dis-United Order, was never released outside of Japan for Xbox 360, likely due to the harsh criticisms it received in the West, often citing It's Short, so It Sucks and having issues with the controls combined with the lack of any in-game tutorials to play the game, much dismay to Western fans. To make things even worse, it is also region-locked, meaning anyone without a Japanese Xbox 360 hardware will have to import one to play the game.
Fan Community Nicknames: Senkonoroids for those who are fans of Senko no Ronde and Virtual-ON, the nickname being derived from "Senko no" of the game's title and "roids" from Virtuaroids.
What Could Have Been: Originally, due to being a Sega NAOMI arcade game, it was supposed to be port to the ill-fated Sega Dreamcast, but it was brought to the Xbox 360 instead. G.rev had no interest on making games for the next-generation systems at the time due to financial constraints. Because of the hardware shift, G.rev had to rework the original game engine from 480p to 720p due to Microsoft mandating every Xbox 360 game must be at least 720p resolution.
Senko no Ronde ended up being an influential game that inspired Orange_Juice to incorporate its gameplay style into SUGURI's spin-off sequel, Acceleration of SUGURI, shortly after the game debuted in arcades in 2006.
When the game made the jump from the Sega NAOMI to the Xbox 360, certain animations and effects were changed in the Xbox 360 version, some not as impressive compared to its arcade counterpart.
