Yes i totally have to agree with you.

Just because someone values Game XY more, doesn't mean that StarCraft II is overpriced.

I am actually quite sensitive about a games price and i had to think about getting StarCraft II a lot. But now that i've got it i'm happy with every cent i spent on it cause it actually surprised me with it's quality.

But yes if you don't play a lot of RTS games it's probably not worth buying it yet, but that applies to every genre.
