I am most likely getting it even though I have 64 and Galaxy. My copy of Sunshine has been lost to the ages per my post in another thread. (I don't have Galaxy 2, bit it isn't in the collection so that's neither here nor there.)
Just to have the games optimized for current TVs etc. probably would have been enough even if I still had my Sunshine.
I am also a sucker for certain games that I will buy multiple times. Not including my sister's original N64 copy, I have three different versions of OoT (and I'd buy it again on switch if they re-remastered the 3DS version for the big screen). I also bought the Metroid Prime Trilogy despite owning all three games separately, and we have the Wii U Twilight Princess and Wind Waker remasters despite owning the originals. So yeah, def a total sucker.
Though one thing I haven't been suckered into rebuying yet is the enhanced switch ports of first party Wii U titles at full price, because that is probably the most offensive aspect of the transition to switch for me.
