totally unrelated but what's that list? (I'm interested in eshop game and I have 0)
I'm only using my 3ds for games so I doubt I'll have issues with space.
NSMB 2, Paper Mario Sticker Star, Mario Kart 7, Star Fox 3D, Fire Emblem, EO IV, Ocarina of Time, Resident Evil Revelations, Unchained Blades (if you want to count it) Luigi's Mansion Dark Moon, Monster Hunter Tri.
The only one I regret getting digitally is Sticker Star as that fell in price right away, though I am one of the few people who absolutely love the game. Was going to buy Style Savvy digitally but literally the day I was going to add the eshop points I found it on sale at Best Buy for something ridiculously cheap.
My new rule is that I'll buy everything digitally that I want right away unless it is ten dollars or more cheaper retail. Even then there are certain games I want digitally no matter what and won't buy physically; including one that has a ten dollar preorder deal right this second in Animal Crossing. The other two are Pokémon X (assuming it is digital, I'll get Y physically when I find it cheap) and Super Smash Bros.
