MFO@ArabiaPlus is a new map especially designed for the new Turbo Random Map game. In Turbo, resources are consumed at a very rapid rate. This map is designed with a little more starting resources, so the rates of advance are quite fast. The basis for the map is Arabia. There is an extra group of berry bushes, 2 extra sheep, an extra boar and an extra herd of deer per starting player. Also each of the players' starting 3 gold clumps have 7 gold units(instead of 7/4/4), and each players' stone clumps have 5 stone units(instead of 5/4). There is also 1 more gold and stone clump per map than in the standard Arabia, and on the medium sized maps and larger, one more randomly placed clump of berries. There are more shorefish in the ponds as well. There is a slight change in forest clump size to help these resources fit better, and there are several different terrain patterns(but no snow). A strictly 'green' version has been released as well(MFO@ArabiaPlus-Green). Besides the resource changes, the map basically plays just like Arabia.
These resource changes seem to help with the fast start and slightly delay the need to change over to farming. The extra gold and stone insure that you will not run out them as quickly. Note that it is possible to do a fast castle strategy (a viable Turbo option) without farming on this map.
