I don't think a 90gb install is normal, but you can see as they release DLC for call of duty that will soon increase, usually 11gb each, 4 of them. Black Ops 3 last year was only about 40-55 maybe, but before I deleted it, it was 86gb in total. So cut scenes explain it? I guess that's why its better to buy games on WiiU or 3DS like Dimensions.
