Hey, hey, no offense meant. I actually don't care that much if material from other games is recycled. If the material is there, and you can make reusing it make sense, I say go ahead and do it.
The modder genuinely seems to care about his work, which is unusual for Moddb. He gives semi-regular updates and seems really committed. Good for him.
It's certainly a better bet to wait for this than to fruitlessly wait for the "real" EP3.
