For me:
Sony first
Ubisoft 2nd
MS
And in the very last place we have EA.
The biggest problem with MSs conference for me was we saw hardly any new games. Gears trailer wasn't too different to the last, FH was FH similar to how any annual or bi-annual games are for me. They are expected and hardly ever surprise or inspire awe. Dead Rising looked good but was leaked early.
Ubisofts Ghost recon gameplay was awesome, For Honour moved amazing, Watch Dogs 2 gameplay was really good, the extreme sports game at the end looked nice and South Park still was the most memorable thing from E3 so far.
Sony just had games galore and didn't waste too much time on games they had already shown such as TLG.
- A new GOW very different to the last with gameplay.
- Kojima game with Reedus teased.
- Crash trilogy remade from ground up.
- Decent VR line up with gameplay and teases
- RE7
- Rocksteady Batman Arkham
- FFXV
- Spiderman
- Days Gone with gameplay (I actually loved the look and feel of it. The sense of urgency and terror along with the destructible environments made for a really intense experience.
You had old school platformer, openworld tps rpg, linear hack n slash, tps survival horror, openworld superhero game and a bunch of varying VR stuff.
