What are the benefits and cons of each? I want each map to flow into the next, but if single player really messes up waits and whatnot...
For a campaign, the only thing that would make single player better is the set next scenario trigger.
Are there any cons though?
Only 1 player can play -.-. I'd go if single player if I we're you. It's more fit for a campaign.
Yes. But I think he means playing it on b.net or single player.
You could probably pull off both, but I always make my games for battle.net. You COULD make it multiplayer on battle.net, that would be sweet.
There differances in Center Screen Trigger and the Escape button in single player Ends triggers (or something like that). I would just do multiplayer or singleplayer lan just because i'm familer with that style.
