Its 1000x more enjoying than looking at standard editions
Having 6 collectors edition is already alot.
You started collecting because you enjoyed the contents on diablo 3, so don't let anything block your enjoyment. Open CE's like a kid opening a christmas gift or keep em sealed and display them as you pleased.
If a particular CE is being talked a lot on this forum, then its one of the things you should get that might increase in value, just a thought lol
Btw how hot is it in Arizona right now? Been having heat wave like shit, taking showers 3 times a day QQ with no AC
