Trading within POTCO led to the game's demise (Disney received 'less' money for UA which in-turn, caused a trickle down effect leading themselves to not value POTCO as much). *On Youtube, "comments" made to videos in support of POTCO trading was epidemic!
~ I do not support TLOPO "trading" because of what I do state above. In addition, when (trading) exchanges go bad...much angst in brought unnecessarily into the community which does not have to be if people would just remain satisfied with what they have!
TLOPO will not charge a subscription fee, so your claim about "the game's demise" is completely irrelevant. If anything, trading would help prevent account sharing, which was an actual problem in POTCO.
