Toxic Brainz by far . <| sep |> Just buy something for him and just tell him you ' re there if he has any questions and you ' re ok with it if he doesn ' t use it . You just want him to have something in case he wants it . I ' d recommended something simpler as smokers are used to simple , high nic , tight draw . Might make the switch easier , you can always buy a nicer set up if he sticks a with it . Something relatively cheaper than an actual mod that might work better at the beginning . If he doesn ' t use it then you aren ' t out that much . Seems like a win win to me <| sep |> You have to factor in 3 rd party in as well . My point is that DKR and MK have similar audiences in that Nintendo would choose to produce a Mario Kart and a FZero instead of a MK and DKR . There are also 3 rd party games like Sonic All Stars Racing with similar audiences . In a 56 console cycle , I just don ' t see Nintendo putting the resources to find 14 different Racing franchises .
