This week, the European Wii and DS Shops' halls are decked, with one festive, holiday-themed game each! Happy Holidays: Christmas on WiiWare is, like the Halloween WiiWare release, a program that lets you put together and send e-cards. Yep.
Just Sing! Christmas Songs on DSiWare is pretty much what it sounds like: a karaoke game in which you just sing Christmas songs. Two of them. Just watch the trailer (via GoNintendo) after the break.
Oh, also, Earthworm Jim 2 on Virtual Console. Neat!
