> Companies like Valve and Epic have already amortized the cost of development of their engines - those are codebases that span 16 years, and both companies had multiple commercial successes. All it took was Unity to give a little nudge.
That doesn't seem to be the case. It seems that UE4 was a pretty major rewrite, and major development is ongoing: https://trello.com/b/gHooNW9I/ue4-roadmap https://trello.com/b/gHooNW9I/ue4-roadmap . Source 2 looks to have been a big effort for Valve too.
- hcarvalhoalves 12y agoEven if they refactor, the point I make is there's 16+ years of know-how, and the fundamentals are still the same (compared to something completely different written from scratch like a ray-tracing engine). BSP, meshes + LOD, lightmaps, occlusion, particle system, terrain editor (since UT 2003)... it's still all there.
