Ive been wanting to complete the G&WG quadrology but i'm stuck between choosing this game and Kirby's Dreamland for Game Boy. I want to know what this fourth installment has to offer over the first three. Is it worth getting whether i have the sequels or not, or is it just more of the same that i can miss out on and get Kirby's Dreamland?
