3DS:
Legit: I had about 10-15 legit games. Mostly MH, Kirby and LoZ titles. Sold most of them, because some of them were a drag to pick up and play (including Majora's Mask (I know, don't hurt me), and FF Explorers - thought it would be good as a MH subsitute, and it was like a "low fat", "low sodium", "low sugar" version of it, and blergh. I also sold my copy of Luigi's Mansion: Dark Moon due to the same thing - terrible mechanics that I couldn't get my head around - and for some reason, people in my area kept on selling it in bundles with their 3DSes...)
Pirated: Mostly games that I can't get my hands on - Dementium Remastered, Terraria...I have a bunch of cia games I dumped and converted myself, so I don't have to carry the physical versions of.
DS:
Legit: again, mostly Pokemon games. I did sell an extra copy of HeartGold + the Pokewalker a while ago to a user on Kijii.
Pirated: Almost every title - except for the shovelware on this system.
