Using UE4 for an office application is certainly unconventional. Unconventional thinking isn’t always a bad thing. Sometimes it leads to innovations. However, can you please explain to us, how it works? I mean, how is UE4 the fastest development tool? Out of the box it’s not even the fastest game engine when compared to it’s competition. Is it fast in terms of actually prototyping ideas and functionality, or is it fast in terms of performance? Because you can write an office program using Visual Studio that will execute much quicker than UE4 will even open.
