my opinion is

if you got extra money, buy.

your a crazy fan or just fan, buy, but cut other spending and put extra on time management.

lack the money, don't, save money and wait for the next time.

it really depend on personal level of financial.
i won't deny its a really great game, easily top the top 10 rts in 2010 chart world wide (or no.1 rank)

all this Rm220 last a year or two disscustion isn't really accurate.
starcrat 2 won't be you only money spend entertainment.
you smoke, movie, date, all cost money.

since op has a sc2 pic as signiture, i guess your are buying it anyway reguardless of what we waid.

so, gg.
