Re: AR in table top games
"Though I suppose it will allow different players to game with each other without the need to actually go to one of the players houses, clubs etc."
That's a pretty big deal for a lot of people. Either your friends have moved far away, or they've settled down with a family, and getting together to play a board game is pretty tricky, with weeks of organising to find a time when everyone can actually get together.
Doing it online (eg, via Tabletop simulator) is one way around that.
