I worked on the team that developed a VR game console prototype for Hasbro Toys in 1986. I also produced software titles from 1978 to 1998 as the software VP for DataSoft, DataMost and New Product Director for ICOM Simulations.
I have a design fora very important title and I am looking for a developer that can create a next-level experience.
In terms of engines and different platforms, I think it's best to contact a trusted and responsible company that will offer the best options. For example, if I need telemedicine app development, then I would prefer to contact inoxoft, because I have heard a lot of positive feedback about the work of their employees.
