Starcraft 2 makes me sad...

I bought Starcraft 2 for the weekend and beat it in less than 24 hours. The story was okay, nothing like the original. The multiplayer is interesting I have only played a few games at that but it just not as addicting as it used to be. My hope lies in Diablo 3, hopefully by then I will have bought a new Mac to play it on. Starcraft 2 runs horrible on my current Macs.
