The price tag is what's putting me off. To be honest, I never played the original Starcraft, although I've seen videos, so I knew what kind of game it was. I'm not sure if Starcraft II is my cup of tea, but if it were priced at $39.99, I'd consider getting it. At $59.99 (or $59.87 if you go to Walmart, lol), I'll have to pass it by. If I knew for sure I'd love it to death, I'd pay the $60.
$60 is definitely pricey (just like all 360/PS3 games), but I think it's definitely worth it. The single player with 26 missions has high re-playability and that's not even half of it; you got multiplayer and other fun stuff as well. If you're somewhat interested in RTS games, I think it's a great buy!
