Besides the obvious differences mentioned by LeBron, there are others:
1. Classes. Speedi and Explorer allow for a radical acceleration of the game.
2. The SoD specialty "LOGISTICS" will provide a very strong advantage.
3. Reorganization of the mages' guilds. The appearance of control provides an advantage, whereas in SoD it could happen that someone gets TP and DD, while another gets Water Walking and Magic Mirror, and in both guilds at that.... You might as well end the game right then.
