Since MMM3 Is is refreshing. Playing MMM3 really pays off here. MMO, Depth is simplyfied, but nice. Staff count instead of various engeneers, not bad. HQ tied to progression and projects are tied tO staff count "Build parts" requires to be rebuilt, as it worns after race - nice. As frequent u change parts, more uprade u will be able to do. Graphically, like that we have models now. Even menu we have slick 3d models. It is better than F1 manager hands down. No money required, complete optional.
