I picked up an RPI3 and now I have to purchase some storage.  Whats the recommended/optimal size of sdcard?  I was thinking of storing a lot of games.  is 128 GB overkill?  I read some people settled with 64 GB.  I will primarily using the storage to store roms.  But I would like to make sure that on the kodi side there is plenty of storage for addons to work.   Thanks
