I go back and forth on this one. On one hand, it does not really add anything and for a long time I did not really use it. There isn't much point without an appearance system (or a more crucial one). ...
I can not stand major clutter in live or build modes, this game already has bugs and issues as it is and the ton of clutter just causes too many time lag and graphic lag glitches. However, when it comes to collectables I like to keep them in moderation.
