In this thread I have seen many good reasons. Keanu Reeves, The Future, Graphics, etc. There's many different reasons. Some of the reasons I'm hyped for it is because the sheer size of the world. It's a massive world, many different districts and many different buildings and areas to explore.

I also have seen some gameplay videos that mainly showcase missions and combat. The missions and main combat system seem to be very complex and in depth. The graphics are actually very visually appealing, the story seems very lengthy and intriguing. There's a massive amount of romance options and who can forget that the game is made by CD Projekt? Those reasons are enough to make any gamer, or anybody really, excited for the game.
