Mistwalker ha tenido problemas con UE3

Y otra más, aunque en esta ocasión se trata de una queja moderada... Mistwalker y Unreal Engine 3:

The issue was that Epic kept updating the versions, so it was hard to catch up. For example, if they released Unreal Engine 3, version 6.1, which has certain requirements and limitations for graphics, you wouldn't have the tools. It was hard to get the tools and instruments necessary to produce the most updated versions of our software.

Also, the lack of bilingual staff made it hard for our coders to get the support they needed. Most of our staff is Japanese, and so the language barrier and the updates made it hard to do. These were some of the issues with the engine for us.
