If you already have 3 and 4...not really, but I got it anyways. And I had all the games. 1 is okay, but 3's superior in every way, and 2 is just...meh. If you don't mind spending the money, you could get it, just don't expect 1 to be as good as many people say and 2 is exactly what people say. --- "Xaldin is a prophet." - lamerhater Anjar elium farakeeu agua.
I bought the HD collection when it was on sale for $20 so it was worth it for me. I really just wanted it for DMC3, 1 hasn't aged that well =S. Considering Capcom sold Okami on PSN for $20, the HD collection was a a good price for me.
