It looks good, but the simulation software used there is more of a game for enthusiasts than it is a serious tactical analysis tool. It certainly does not use high fidelity missile or radar modelling and it does not contain the (highly classified) RCS data that a lot of the shots in the videos would need in order to model the flyout accurately.
I wouldn't put too much faith in the kill ratios claimed there. Unless, of course we really can swap billions of dollars worth of scientific wizardry for a £50 game.
