tons of quality mods will be out too, already in beta some amazing mods were done.
single player speed might be just normal.
online ladder is Faster mode, but u get 5 practice games you can play in normal mode, the practice mode also has your based wall in with rocks, so you wont get rushed (unless u get rushed by air), you can skip this option, thats what i did ^_^.
Also the blizzard help system is very impressive, the tech tree guides/etc are very well done.
As Zerg i got some good strats nailed out
, so ill be hitting Multiplayer right away, and at the same time testing out the SEA servers
