While on a day trip I lost my DSi and a dozen or so games.. Didn't want that to happen again,
Now I use it for games I already own hard copies opf and more importantly guides.
I don't feel I really own it until I have the case, instructions and physical cart. I built a high wall display for them... It's not out of any sense of honesty, just like owning something I can sell later for a profit. and not lose... I have used it for demo trials though and have bought most every game that I kept from downloading, (when poss.) as the price drops below $5. USD, which is quite a few these days... if you know where to look. Still buying them today... I know it's redundant but in the event of an unexpected update/card brick etc... I can still game on... without missing a beat... locally the physical games are quick cash in a pinch, roms are not. I have even been known to buy more than 1 copy of a game I really enjoy to support the developer. I figure if they don't get numbers and know we're interested, they stop bring games over here. I'm looking at you FireEmblem...
