4.5 stars - my favorite of the 1944 stories nominated for Retro Hugo awards! You can read "Arena" free online here or here . Review first posted on Fantasy Literature , together with reviews for ALL of the current Retro Hugo novelette and short story nominees. Seriously, this FanLit column took me HOURS to put together, even though I didn't write all of the reviews in it, so please scoot over there and take a quick look and let me know if my efforts paid off. Feel free to add a comment to the thread there. :)So, "Arena":Two huge space fleets near Pluto are about to engage in a battle to the death: Humans and the aliens they call the Outsiders. Bob Carson, a young human in an individual scout ship, is about to engage with his Outsider counterpart in another scouter when he suddenly blacks out, only to awaken under a dome on a planet in another dimension. Across from him is a large red ball with retractable tentacles that turns out to be the Outsider scout, and the two are separated by an invisible barrier.A disembodied voice informs Carson that if the space battle ensues, one side will be wholly exterminated, but that “winner” will be so damaged that it will “retrogress and never fulfill its destiny, but decay and return to mindless dust.” So this powerful entity has plucked Carson and the Outsider out of the two fleets to fight a one-on-one duel to the death. This being will destroy the entire spacefleet of the loser, allowing the winning species to continue to progress. But given the invisible barrier between the two, it will be a battle of brains as much as physical strength.I first came across "Arena" at about age 13 in The Science Fiction Hall of Fame, Volume One, 1929-1964 , a book that was instrumental in shaping my love and tastes for SF. "Arena" was one of the most compelling and memorable stories in the collection, and rereading it now, a few decades later, I’m impressed with how well this novelette has withstood the test of time. Compared to some of the other Retro Hugo nominees from this year, it’s an outstanding piece of storytelling, and there’s a nice note of irony to the ending."Arena" was used at least partially as inspiration for a famous Star Trek episode in 1967 (also called), which has a quite different ending. Many prefer the Star Trek ending, and I can't really argue with that, but considering that this was written during WWII, when the mood for righteous war was at its peak, it’s impressive that Brown actually took the time to show that Carson does attempt to make peace with the Outsider, which responds with a wave of hatred so strong that it physically weakens him."Arena" may be somewhat lacking in depth and nuance, but as a suspenseful, well-told SF action tale from this era, it’s hard to beat.
