Its fun to get recognition for the work or tasks you have completed.
If you are playing on a Microsoft console you will get achievements which have a number value and if your playing on the Playstation system you will unlock trophies.
You can read the name of each trophy or achievement so that you can select which one you want to unlock.
I play randomly unlocking as I go along rather than picking and choosing which one to unlock.
How do you go about unlocking achievements/trophies? Do you just randomly play unlocking them as you go?
