i divided into 2 categories, games wise and console wise.

i'll ask u, do u willing to invest RM100 to RM300 on da game (game wise)??
again, do u need all da fancy function available in ps3/xbox/wii?? (console wise)??

u did mention dat u r not dat rich, so would u spend 1k on da console and in d end sold it bcoz u cant afford latest game? u answer ur own question d..

set aside cost for the console, most of da ps3 owner here oleady spend between 1k to 3k (depend on how hardcore they r) on game only
as for me, all of da console hav their own pros and cons. u wouldn't lose anything if u choose wrongly
