The player community is of pretty good size compared to the budget levels of the game and all that.
Best way to get an idea of the size is to check steamcharts which track active players.

So a year after release there are between 500 and 1100 people playing the game at any given time. Back when it was released it had a peak of over 20,000. That's a comparable number to something like Batman Arkham Origins. Not too bad for a turn based RPG.
