But, I am interested in the costs of WOW Classic TBC Gold running the servers and the development tools needed for this, and the support teams for whatever follows.

Everyone claims that everything is free, and Blizzard is requiring us to pay. This isn't the case.

This is the way to view it. Support was always available to help with every version of WoW. Then you can include the classic. While it's likely to increase the workload but it does add many new things. We're currently adding tbc...again expanding the support roll for teams that require it.

It is reminiscent of Harry Potter's chocolate frog playing cards. If they decide not to offer physical copies of the game, it would be great to download an app for your smartphone or cheap WOW TBC Classic Gold wear smart glasses to look at your collection. They wouldn't be a burden on your space and could be customized to include collector's additions. Are you certain that this is a great idea? Or am I getting way too optimistic?
