I really like the Ambassador program. I know they already have the NES stuff on the Wii but I when I got cards I was always more interested in getting the Nintendo 64 stuff instead. Having 10 more games on September 1st and beyond on my 3DS will help ALOT. Plus if there's any updates to any of these games we also get those for free. Not to mention that eventually we'll have 10 free Game Boy Advance games some of which may never be released to the public.
Yeah, plus the free NES games are portable. The GBA ones have always been portable, but at least I might not have to drag around my GBA with my 3DS to play some of the GBA games I like. 20 games is a lot. I'm going to have a lot of stuff on my 3DS.
