For anyone thinking about buying this game I can honestly tell you that this has been one of the most enjoyable purchases I have made on steam. The workshop mods alone make this game well worth the price. I started first looking through the steam workshop and found that any tabletop game I could think of was there and ready to play. Which is great because it is rare I have all my game playing friends anywhere near my tabletop collection. So its nice to be able to roll some virtual dice and play some board games online.
The gameplay can be a bit awkward sometimes (kind of depends on the game) but use the hotkeys for functions like, lock down game piece, or zoom in on card, can really help speed up game play and keep you from knocking pieces all over the board. If you do manage to destroy your board or someone gets mad and flips the table, you can simply undo step and the board has been reset to the last play before desaster struck. Another thing you might wonder about is hiding your cards so other players cannot see them. There is an area over your "seat" that you can place cards without others seeing, however if you need a larger area simply use the fog of war tool and your cards are safe from other players view.
In the time I have played Tabletop Simulator I have purchased a few tabletop games that I wouldn't have otherwise, due to the cost of some tabletop game titles. Being able to try them out with expansions and get a feel for the game really made the difference for me and I then had no problems sinking the money into the real thing. The game is constantly growing with more from the workshop and polish from the developers. Once again this is well worth the investment and has endless reply value.
