Which franchise is next for Retro?

[DarkCronos]

i wish they could go back working on metroid. i loved the prime trilogy, but since it's a closed chapter and they are doing 2D pltaformer like DKCR, i wish they could do a real 2D metroid, not that sort of abomination that other m was.

 

i would also love to see some original ip from them.
