Gamers Hell interviews John Fuhrman, Director of International Development at E-Pie Entertainment & Technology about Vietnam War: Ho Chi Minh Trail, their upcoming FPS set during the Vietnam war:

    Tactical combat simulations usually have to straddle action with realism - how have you found the equilibrium between both in the game?

    One thing that put realism and action into balance is making it a fixed-position game. That way we eliminated the need to constantly render an ever-changing background, which allowed us to give animation of enemies more clock cycles. You'll find that in a field of attacking enemies, gunfire, napalm, mortar, and artillery all have different effects on different bodies, giving the game both action and realism.
