Everything JackAlvin said resonates with hard truth btw. This game truly WILL be costly once the other 2 'expansions' are out. Totalling abt Rm660 is a conservative guess, id say RM750 if ur unlucky.

Pricing aside, as well as the poor campaign storyline (Well, im not interested in Raynor much tbh) you'd best ask yourself:

1. Do i want a competitive RTS arena? Where losing is a culture and mastering the game is my goal?
2. Do i look forward to becoming a pro-gamer in Starcraft 2? Or am i simply playing it casually for friendly matches/mass army slugfest?
3. Is bleeding-edge next gen graphics is important to a game? Or the gameplay aspect of it?
4. What is MY(In this case, you) idea of fun?
5. Do i like ANALYZING in a GAME?

I'll be frank, as one who have purchased the game myself i highly discourage any casual gamer to buy the original. Just wait for the pirated version to be out and play it for the campaign or LAN parties at cybercafes. Starcraft 2's multiplayer is extremely competitive in comparison to other RTS out there and thus have a tendency to give bad vibes to casual gamers who find it hard to have fun with the game's multiplayer aspect.

-However-
If you're like most of the Starcraft 2 players who are in it for the competition and challenges of its multiplayer, then this may be the right RTS game for you. Do note that Starcraft 2 is a high-profile game, so prospects of being 'known' in the gaming arena is great...if you're a great player.
