Starcraft 2 - worth buying?

[--Pete]

Hi,

...as someone who'd never played SC before, my eyes began swimming before me after even 3 pages about Raynor, Kerrigan, Raszagal, Duran doing god knows what against who knows whom and what knows what in every different possible combination of alliance and double cross.

Yep. Even playing the original through the single player campaign I got confused. Maybe there's a Cliff Notes version -- I hate having to take lecture notes in a game.
