Worth noting that a lot of games, especially popular newer games, are primarily played on TTS or Tabletopia or some other VTT. None of those has a complete ASL set, so VASL has the market cornered.
X-Wing gets a lot of play on TTS I've noticed.
Also worth noting that the fully-realized 3D components, and the interface used to manipulate them, is currently better suited for games with minis, cards, tiles, etc. than stacks of counters. Most wargames are still a bit klunky on them compared to VASSAL.
