We've been asked by some close friends about our opinions on video games as Christmas gifts, mainly to the elderly. To be honest, apart from the Brain Training and Professor Layton series on the DS, I can't think of any video games suitable for elderly. I haven't been following the DS scene for some time to be honest, but a cursory glance on DS charts seems to confirm my suspicious that those two series are the only ones worth getting as gifts for the elderly.
As for getting video games to other target audiences, I have a couple of suggestions. SingStar series is always a great gift idea as only the most thick skin person would deny its entertainment value. It is also perfect for post-Christmas and New Year Eve party where booze is readily available. For your average surly teenager I reckon something like Uncharted 2 or Left 4 Dead 2 would be welcomed - provided he/she hasn't already played it. Something newer like Assassin's Creed 2 is probably a safer bet.
For those who likes to play with their (very) young kids, may I suggest EyePet or Rabbids Go Home. They aren't terribly exciting, but will surely entertain those (very) young kids whilst keeping the adults amused (for a while). And finally if you have none-video gaming loft residing (e.g. Bermondsey) friends, then I am sure Wii Sports Resort, the new Zelda, Mario & Sonic or something silly like those overpriced toy guitar games will be appreciated (even if it is silly).
