Gamebryo vs HeroEngine

Gamebryo has been written in C++. Because its features are as independent of each other as possible, it allows including only the features that are necessary for a game. Also because the abstract interface and its implementation are separate, custom implementations can be made as well as default implementation extended by inheritance.

Gamebryo supports Windows, XBOX360, PS3, and WII. Several hundred cormercial titles have been developed with Gamebryo, including The Elder Scrolls IV: Oblivion, Fallout 3, Catherine, RockSmith, and etc.

Gamebryo has detailed documentations. It is provided in html files and its size is about several thounsand pages. It also includes several dozens of tutorials and demos.

Backend completely handled by the team at Hero.

No need for Perforce, Github or any other versioning software. It is built in. Check, Compare, Merge, revert, etc.

Developers of the engine and game developers are active on the Forums and Skype for private messaging.

Able to create many types of games and scales all the way from a single area up to a full-blown MMO.

Designed for the needs of a MMO. HSL is also relatively easy to learn as scripting languages go. It was geared towards beginners, not time hardened programmers, and as such, its easier for a novice to pick it up sometimes, than a c++ programmer. That, and it was intended to be "readable" more like English.

Skype channel and forums questions answered by developers of HE and users very quickly.

Though the export pipeline may be different and currently requires 3ds Max or Maya, the format is highly optimized to reduce high quality models down to KB's.
