It actually doesn't matter that much to me. Usually I always enjoy a reveal of a game that I'm waiting for. However I don't like when a game comes out a few days after the reveal. There were a few examples of that (e.g. Fallout Shelter or Gwent: Rogue Mage). This doesn't build a proper hype and is simply less entertaining. If I'm waiting for a game, I like to watch some trailers before it's released, read about the gameplay, see screenshots, discuss all these things with friends etc. When a game is released almost instantly after the reveal, there's no room for that. Developers that release their games instantly resign from a free marketing campaign.
