"Indie" game engines vs De-Facto 3D game engines

"Indie" game engines do not have the stability/past performance record to achieve the required stability for professional applications. Factors of security, functionality, re-usability. tutorials, user knowledge has been acquired and built for over 10 years. Why try to invent the wheel; just find new ways to use it, is the challange now. Costs; we can provide a be-spoke VW using web.alive from £25K and can host for around £1K/Month for 20 peak port users. Why bother to create your own?
