What kind of games do you like? There are strictly Christmas games out there. But there are even more games that have a Christmas theme to them coz of the holidays. Tiny Tower, Subway Surfers, Clash of Clans and Verticus are just some of the games that have been updated with a holiday theme. And as you can see, those four are quite different genres of games. Please specify preferred genre.
Junk jack and ski safari are really feeling Christmassy to me.. It's kinda nice when you don't celebrate Christmas to at least have the Christmas feel in the games you play.. A Christmas update is coming for ski safari..can't wait!
Something like Jazz Jackrabbit or Hugo: Winter Games 3 Just, something with good christmas atmosphere
