I've done quite a bit of gaming in virtual tabletop environments. I did a lot of conversions for TFT stuff for the CyberBoard program, which hasn't been updated since 2010.
I've done a number of the Dark City Games adventures in
VASSAL and may do so for some of the new TFT material when it's released. It depends on the status of VASSAL's development, which seems stagnant. I'd love to find a cross-platform open source system that's in current development but haven't dug too deeply.
I prefer playing programmed adventures using a VT as it's as portable as my laptop and there's no chance that I'll
- spill anything on the board and pieces
- lose something when traveling
- forget where I am in the game
