Well the install for titanfall was justified beausese of it's lengthy cinematics, it's long single player game, and it's rich fully fleshed out story.
Incorrect. The devs themselves said 35+ GB was used on the PC for nothing more than uncompressed audio files. Titanfall on Xbox was only 17 GB. Their excuse was that they felt the older dual-core CPUs wouldn't have enough horsepower to uncompress audio on the fly. Thus even if you had an i5 or i7, you were still forced into having the uncompressed audio on your drive. I believe that also included all the language packs, meaning you couldn't even save space by only installing the one language you wanted.
