I had something similar happen with Battlefield. I had bought the disc despite owning the digital *was having net issues at the time* and when those got cleared up, I traded in my disc and attempted to download *still having the installed data on my hard drive* but instead of allowing me to download it just said Start Game in the download option's place. Tried to launch the game but it told me to insert the disc. Really would be helpful if that was an option, to use that install data...
OK, so after I deleted the disc installed version and redownloaded the game it started up this time. But this evening I was trying to get a game going with my kids and after loading the game save it says I have to wait for install and it is at 40%. It never moves from that spot. I've had issues with Knack (disc-based version) where nearly every time that won't start because it has to install and it sits at 0% the whole time. I have to delete the disc install and redo it nearly every time.
So I just deleted Lego Marvel once again and am redownloading it. I noticed that the file that downloads is only 900 MB while the game is 6.x GB. So I guess that is the "initial" install that lets you play the first level or whatever. But the problem is the rest of it is not downloading/installing.
My conclusion is that the whole next-gen "play while downloading" thing is way too glitchy and in effect total BS. I wish they would just go back to downloading and installing the whole thing before you can play like on the PS3. I have never had DL/install issues there and they seem to be constant on the PS4. Now I'm going to get this partial install and will never know if the thing is fully-installed or not until I try to play and it tells me it isn't

.
I have 4 "full" games. Knack gives me problems all the time like I said and now Lego Marvel is flaky. I don't seem to have problems with NBA 2K14 and Skylanders though. And the PSN-type games (Contrast, Don't Starve) work fine.
Edit: Yep, redownloaded that first part and now it is still just telling me "40% installed". It could be that it needs to download the other 5GB and that won't change until it is downloaded and installing. However, here's the big problem: nowhere in the game or even the system (including under downloads) does it say it is downloading anything at this point. My router seems to be flashing like crazy so I guess I just need to wait an hour to see if it downloads the rest and finishes

.
So that's the big issue: I just want to download the ENTIRE game before I play so I don't have to wait for more downloading when I'm actually playing it. It seems what this game does is
only download the initial part and then it downloads the rest after you start playing. That is absolutely asinine. Can we just not do this sort of crap, devs? I specifically set up the download earlier when we were doing other stuff so we could play it this evening but it only did the small download and then apparently stopped. And now it is making us wait when we want to play. Stupid.
