I've noticed that there aren't that many hetalia games out there with a sci-fi aesthetic. Mostly fantasy (like tales of hetalia) or horror (like hetacorpse). Yeah, there's hetahazard and hetapocalypse, but those deal with zombie apocalypses. I think there's a shooter out there based off hetalia with japan as the spaceship flyer, but it's only in Japanese and there really isn't that much besides shoot the enemy ship. No, I'm talking some good-old star wars, Metroid, xcom-esque sci fi. So, I have an idea to fix that.
Mass Effect is one of my favorite video game series, even with the flames surrounding ME3's endings. Deep world, great character
