Right now with an 8GB SD card I have two full 3DS games, all 20 Ambassador games (10 NES, 10 GBA), Donkey Kong Original Edition (NES VC). 7 eShop games, 12 demos, 8 trailers, 5 GB VC games and 1 GBC VC game. And I have tons of space left. I recommend higher though if you plan on going all digital like I am, you never know if you'll need the space and cards are pretty cheap! --- I don't see Nintendo, Microsoft, Sony. I see Mario, Zelda, Uncharted, Resident Evil, Gears of War, Alan Wake, Heavy Rain, etc. Play games, not companies.
