I agree with you . As per my opinion Sometimes it becomes necessary to delete some of the information stored on your memory card so that you can store new information.
Every game that you have either finished, or don't really enjoy anymore. If you want an example, id say BIA2
8GB only really has like 6GB of memory available for apps. Each app, especially large apps with a few hundred MB, usually doubles or triples their space when installed. I only have two large apps on my phone and left with only 300MB free space, Chaos Rings and a GPS. Lol with "8GB" you can hardly do anything.
