Personally, nothing gets me more excited than when I go on YouTube and see an OFFICIAL gaming trailer for an upcoming release. I know gameplay isn't going to be like in the trailer, but I do get genuine happiness for upcoming releases.
For 2018, I'm looking forward to Ace Combat 7 - Skies Unknown. The 6th installment really lived up to my expectations and more. So I'm hoping the newest one will do the same. For FPS action, I'm looking forward to Blackroom. Personally, I've heard mixed reviews (good and bad), but I want to try it out myself when it's released. Darksiders III is also being released next year. Darksiders II wasn't really the same hype as the original. So I'm hoping the 3rd installment will make up for lost hype.
