Just that really. DS15 loves gaming. He has PC, great monitor, headphones, earbuds, gaming chair. He has a bike, likes to walk (has a newish fitbit), not really into clothes but happy with clothing he's got (loves his hoodie which is newish). I have no idea what to get him for Christmas.
We usually go for a main present (hence the above equipment he's got already) and lots of little stocking fillers. Am thinking cash seems the only option as I don't want to spend £200 for the sake of it.
