Elite: Dangerous - basically a dream come true, never thought I'd see the day. Elite's a love of mine since early childhood.
Space Citizen - same as Elite, the renaissance of space sims. Can't wait to get bored of space.
No Man's Sky - same as the above, but the concept promises even more, even if in a somewhat less complex package.
...and pretty much all upcoming space sim games.
Quantum Break - love everything that Remedy's done so far and I'm sure it's gonna be an interesting game, to say the least.
MGSV - just finding out if Quiet=Chico is enough of a sell for me.
Hotline Miami 2 - the first game set me in an obsessive, hypnotized state for a few days, the most addictive and mind altering game I've played recently.
The Witness - played quite a few first person puzzle/exploration games recently (NaissanceE, FRACT OSC) so I feel like this sub-genre has completely grown on me, can't wait for more stuff like this.
Rime - don't really know much about it but the gorgeous visuals and Ico-like feels make me really curious about this.
Below - pretty much like Rime, visually appealing and sounds like it could be an addictive game.
Routine - cyber horror on a space station, System Shock 2 vibes all over.
I mean, there's more stuff like Alien: Isolation, Quadrilateral Cowboy, Civilization: Beyond Earth, Armikrog, The Order 1886 etc. but I'm more curious about some of them or still know too little to make a judgement.
