Those games...well...they suck. At least the ones that are coming out for this Monday. A personal preference perhaps, but not very intereted. I have never played Ristar so I really can't comment on the quality of that game.
It would be cool if they released a some special addition to the VC library on Christmas. There have been rumours floating around about secret stuff planned for WiiConnect24, so it will be cool to see what comes out of it.
