Tabletop Simulator is a popular choice for miniature wargaming. 'Builds' here refer to army lists and terrain layouts. Import 3D models for your miniatures and use the 'Gizmo Tool' for precise placement and rotation. The 'Measure Tool' is indispensable for determining movement and attack ranges. Many mods offer pre-built terrain pieces, or you can import your own custom terrain to create immersive battlefields for games like Warhammer 40,000 or Age of Sigmar.
