Well in the pictures ,it's good lightmapping,
some tools can do that , Blender can bake it !

For games with lot of action where you look at ennemies instead
of exploring static world : You don't need incredible Lightmaps , vene players will never notice if lightmaps are precise or not !

For 1500$ : Sorry but for arcade games, casual no need !

In fact that lightmapper is really for scenes visualisation,
where the user stand on the scene visualizing it hours !
Not sure it's incredible for games

For gaming no need,and solution already exists, seems to be some trick from Garage games to make more money
