Well with the name and advertisement can you blame them, it looks interesting though.
I still fail to see how it sounds like a gay porn.
Denpa, from the Japanese word for Radio. Japanese title being Denpa Ningen RPG, so literally radio human role-playing game. (after watching the
Ryuusei no Rockman anime, I noticed they say
denpa ningen a lot because of what it means)
The Denpa Men, obviously meaning the same thing as the original Japanese title.
They Came By Wave, referencing the fact these Denpa Men come and go via radio waves.
The advertising may help, but the title... you're stretching it if you think it sounds like that. Either that or trying to bandwagon with Archer who started this whole discussion.
Still, try the game out (there's a free demo on the 3DS eShop that lets you save at any time and transfer your data to the full game) before shunning it just because you find some issue with the name.
