Developers switch for better 3D graphics, larger Asset Store, official console support, and more job opportunities. Gain: mature ecosystem, extensive tutorials, VR/AR support, industry adoption. Trade-off: seat-based pricing after $200K, trust issues after runtime fee controversy.

AAA developers switch for Nanite, Lumen, and photorealistic graphics that Godot can't match. Gain: industry-leading visuals, free until $1M revenue, massive marketplace. Trade-off: steep learning curve, C++ required, heavy hardware requirements.

2D developers switch for purpose-built 2D tools and gentler learning curve. Gain: drag-and-drop + GML scripting, proven for 2D hits (Undertale). Trade-off: subscription model, limited 3D, smaller community than Godot.

Mobile developers switch for smaller build sizes and King's backing. Gain: lightweight, excellent mobile performance, Lua scripting. Trade-off: primarily 2D, smaller community than Godot.

Non-programmers switch for visual/no-code game creation. Gain: no programming required, fast prototyping, good HTML5 support. Trade-off: 2D only, less powerful than Godot, subscription model.
