Well I don't have a modded Wii, so i'll have to buy them if I want any more. I've already got Defend Your Castle, I don't think I need the other ones.
You just need TP and WAD Installer by waninkoko.
I just buy and read before you buy. Like Reviews
Problem is, not everyone is like the reviewer, that's their personal opinion. Trying before you buy is much better than just reading a review.
From the reviews, people said SMG was like a Godly game. I found it a bore fest after doing the same level 3 times.
