I got all my E3 coverage elsewhere.
Basic rundown:
Fallout 4: Takes place in Boston, you can make shelters, add onto weapons, improved DOG mechanics.
DOOM Remake: Don't really know. Didn't really care all that much.
Squeenix is broke, so they're remaking Final Fantasy 7...
...which is weird since they also announced Kingdom Hearts 3, which should get them a decent amount of money
Nintendo's been releasing things left and right for the past couple of years, so they didn't do anything special for E3
Ubisoft sucks so who cares.
And a bunch of Indie devs showed off their games.
