Might be the catalyst for me to upgrade from DS to DSi. If they get Astron Belt I am definitely in.
Old arcade concepts never die - they just end up converted. I got my 5 year old playing Sonic #1 on Wii today to alleviate his out of school boredom. OK, not an arcade game, but he's a big MAME fan too.
Of course, had it been me, in the 1970's when I was five, my alternative to Sonic or MAME would have been learning to rake leaves. Back when kids never dared to admit they were bored.
