1. Metal Gear Solid V
2. Destiny
3. Bloodborne
4. Zelda Wii U
5. Smash Bros Wii U
Metal Gear had an excellent trailer AND gameplay to along with it. Cant argue with quality or any of the insane attention to detail in Kojima's work. Thought it had the overall best showing.
Destiny is still too cloaked in mystery for my tastes, but the art direction is top notch and Im a huge Bungie fan. Plus gameplay, so points there. Would sell me a new system.
Bloodborne is basically just a trailer, but the pedigree is of such weight in this case that I really dont care. I need it. Likewise, Zelda Wii Us trailer hinted at everything I want out of a new Zelda. I need it too.
Lastly, while Smash isnt revolutionary, I appreciate them letting fans play the e3 demo and think it was an awesome gesture. Kudos for the great showing, Nintendo.
