I like titles that do try to reference stuff that goes on in the piece, like, say, Warframe - it's nice, simple, and tells you what the game is about. You're at war, you wear a frame, problem solved.
Others are:
Space Pirates And Zombies - you're in Space, you're a pirate, and you fight zombies. Beautiful.
Sunless Sea - You're a sailor on an underground sea, ergo a sunless sea. Much more evocative than the browser game 'Fallen London' (same universe) since, well, there's a lot of ways for London to fall, but not a lot of ways for a sea to be sunless.
Transistor - It loses points since the Transistor in-game doesn't really do a whole lot of transisting (given it's a big fuck-off sword), but it gains points by invoking ideas of electronic imagery with a single word, which the game utilizes beautifully with it's art style.
Wolfenstein: The New Order - I know, the colon is there, but the title works well since the game is about 'the new order', as in, the new order of things after the Nazis won the war.
Spectrobes: Origins - Fuck, a colon and a buzzword, but this one gets a pass from me because it actually deals with the Origins of stuff in the game as opposed to just slapping it on there because they needed a marketing term. That's a god damn rarity these days.
Paper Mario And The Thousand Year Door - a long one, but it works with the games stage-show presentation by sounding more like an old-timey movie rather than a video game title. Plus, you play as Paper Mario, there's a big fuck-off door and it's approximately a thousand years old. Boom, gives you everything you need right off the bat, fucking majestic.
