Have had a white lite since they released in the UK. Have had to exchange it once due to hinge crack - somewhat well documented error found in whites.
Currently I own, Dr Kawashima's brain Training, Metroid Prime Hunters, Mario Kart, Action Loop, 42 All Time Classics, Contact, Transformers:Autobots, Pokemon Diamond, Settlers, DS Browser, Zelda Phantom Hourglass
I have also owned Goldeneye: Rogue Agent, Lostmagic, Age of Empires, Star Trek Tactical Assault, Star Fox. Of the latter lot, they gameplay just wasn't long enough to warrant keeping and I could get a close enough trade in price to what I had paid (Starfox is a good game, but too repetitive)
If I were to swap any I would get rid of Transformers and Contact as they don't really have the gameplay. Sadly, I would get very little trading them in, so haven't.
Zelda was far too easy/short, but I have completed every Zelda released in the last 10 years.
As a general rule, Nintendo licensed games are a breed above the rest.
