Yep. Never owned a Nintendo console before, bought the Wii as a (joint) present for my dad. It was kind of his idea, he saw the advert for Wii Sports on the tv and said 'wow that looks like fun', so we decided to get him one for his birthday.
Personally, I prefer to play the PS3 we have, but Wii is great for older members of the family to get involved. I bought RE4 for myself, which is fantastic, but I'm going to hold off getting anymore games for a while (I'll buy them as presents for family members - another bonus of having all the family involved, you can buy them presents you will actually enjoy as well :D ).
Smash Bros, Mario Kart and Zelda are the ones I intend to buy though.
