I'd like to hope that getting SMB 2 at its discount price now would prove beneficial with regard to any potential deals similar to this one down the road.

ie: Own SMB 2? Get SMB 3 half price. Own SMB 3? Get SMB half price. etc. etc.

I've been on the fence for getting Mario World on Wii U VC. With the added 50% for SMB2, now's the perfect chance!

Also got Super Metroid.

...Er, I don't see why people would go back to Puyo Puyo for online because the online capabilities were already covered in Puyo 7 & 15th. I guess it's for the super die-hard fans who don't want offsetting (which I don't understand kinda.).

Well, it's a step at least. Here's hoping to more in the future.
