Stride deserves a trial if your team wants a C#-based 3D workflow, but test shipping before committing. Build a small playable scene in Game Studio with imported art, input, UI, lighting, and one saved setting.
Follow the Stride documentation for the exact version you install. Note how long it takes to change an asset or script and see the result. Add a second scene and let another developer clone the repository and reproduce the build. Check package size, startup time, graphics quality, and performance on the weakest intended device.
Compare license, ecosystem, updates, and support with other engines on the shortlist. If a plugin or platform export is essential, prove it works in a pilot rather than relying on a feature claim. Keep assets in interchange formats and record any engine-specific dependencies before migration.
