I've liked the value of this service a lot but never had a reason to sub until now...Titanfall 2 just entered the vault.
I've had my eye on that game to just wax the campaign for a long time, but I never wanted to spend $20-$30 to buy it, and redbox rentals are too short a time for me (conversely, can get expensive quickly if you keep it a few extra days).
So I subbed to EA Access just for TF2 campaign now, essentially used this way it's it's a 30 day rental for 4.99, which is fantastic.
Unfortunately there isn't any "stream while you download" or anything. I have to download 66GB the full game to play (well you can play the tutorial over and over after like 30GB, big whoop.jpeg).
I'm actually capped at 250GB/month by my ISP. Normally I dont threaten this, even with tons of Destiny/Twitch viewing/youtube etc etc. But full game downloads can really eat it fast. Well, not a hard cap, but after 2 violations (I have 1, which is because of a month where I uninstall/reninstall Destiny once or twice at 70GB a pop) I think they're gonna charge me, probably 10 bucks or something, no big. I get 50 mbps down. They offer 100 down/350 cap for +$10 per month (paying $57 now), 200 down/unlimited for +$20, etc etc. But the caps do seem pretty low at the bottom there.
