By way of apology to early 3DS adopters after slashing the price of their new handheld a few months into its life cycle, Nintendo promised to provide twenty free games and special Ambassador status (that comes complete with a shiny virtual certificate). The first ten games were made available without incident, but since then, Ninty clammed up about the second round that includes classic GBA titles. Today, though, ONM has received confirmation that the next phase "will be available before the end of December 2011," and more details will be announced "in due course." We'll keep a watchful eye on the situation.
Yoshi’s Island: Super Mario Advance 3, Mario Kart: Super Circuit, Metroid Fusion, WarioWare, Inc.: Minigame Mania, and Mario Vs. Donkey Kong have all been confirmed for the second round, with five more to follow. As far as I know, the online ambassador registration tool is still open if you haven't already claimed your free games.
In other Ninty news, the price cut has apparently allowed the 3DS to outstrip the first year sales of its predecessor in only eight months. Considering that Nintendo has been under fire from pundits and shareholders alike, this is great news for the beleaguered company.
