What are the differences between OMC 3 and OMC 4?
OMC 4 only supports C&C3 at this first part, unlike OMC3 which supported 3 games. Mappers are no longer restricted to one submission. Now they can submit as many maps as they wish. The way the judges will rate the maps is also changed with a more specific guideliness behind the scenes. Following the tendency of previous contests more harshly, symmetrical maps are no longer allowed. The submission time is now 2 months and a half. There will be more games as prizes for the top 3, however, no money, since we need to pay shipping costs.
