I do agree that there are similarities with sci fi such as Mass Effect. Also the use of food replicators and Warp drives reminded me of Star Trek. Humans and Predators both have these technologies.
And I noticed many of those Mass Effect similarities too. You gotta admit though, the Mass Relays are much safer and take you further away than Dropholes.
I'd rather use that any time if I were a space traveler lol.
Despite these similarities, I like that Lebbon used a bit of his own personal touch. Such as making Dropholes extremely dangerous to construct and exceedingly risky to use with a guaranteed doom for anyone whose suspension pod has failed to work properly during a drop.
