Further observations from this site:

Instinct you were asked about it even by Rock, Paper, Shotgun the question was:
"Is it still using the GEM engine? Isn’t that engine getting a bit old now? How much can you actually improve on it?"
You answered it there but the toughts about it are:
You have 1 person which is responsible for programming according to credits from MOWAS2.
You have "sixteen times the level of detail" compared to what ?? Soldiers Heroes of WW2 from 2004 ?
The today visual standards are absolutely elsewhere for example most noticable change like paralax/bump mapping was curent 7 years ago.
In other words what you curently do with this obsolete middleware engine is only chasing the competition better said time. The year where you actually stopped at the moment is year 2005-2008... Today is 2014 and the competition stands not on same place of course.
