why is Real Racing 3 consuming 3.2gb internal storage?

[AC Question]

Google Play services is within norms. Every day internal free space diminishes by a few Mb. Nothing is kept in the phone and the SD has ample space.
I've been dealing with this for 2 months and about ready to trash Real Racing 3 for good, which is the ONLY DOWNLOADED APP INSTALLED. All pre-installed apps have been disabled or uninstalled. Total data is 3.25Gb used by RR3 and only 38Mb free internal. Abolutely no room to update Google apps or even the 5.1 Android itself cannot be updated. This is a brand new LG RISIO. 16Gb external SD. I prefer not to factory reset but this seems like the only option to clear what ever hunk RR3 has installed.
Will an app manager control this runaway app?
Firemonkeys and EA have been negligent in responding to support tickets.
RR3 is my one and only game to play, nothing else compares to the graphicsgraphics.
I REALLY NEED HELP SOLVING THIS ANOMOLY.

Are there add-ons in the game that you purchase? Also, you may be seeing cache consume memory. Take a look at the storage usage for that device and see if it's cache or app storage consuming memory.
