My advice .. Watch some of the videos for TTS ... it is not about being at an immersive table, it is about a speeding up play while keeping all the detail. A good group with hero system knowledge can play around 30-40% faster combat encounters when used to TTS hero mod, in a 3d environment which can give a first person view of the action which lends a unique perspective.
If you want more detail join the hero system discord channel and talk to some of the playtest teams using it.
