Yeah, it's nuts to me. You're renting a handful of N64 games (and some Genesis re-releases) AND DLC.
The N64 is a strange one to me now. A lot of nostalgia for it as it was my first proper system besides my gameboy. Both Zelda games and Starfox have excellent enhanced 3DS remasters which you can play on that system or emulate for even better results. Both Turok games have excellent enhanced remasters, I never paid them any mind back in the day but they more than rival the other FPS's on the system IMO. The excellent RARE Replay has a lot of their N64 games and a pretty much perfected Perfect Dark. The leaked version of the X360 Goldeneye was amazing as well. Played that earlier in the year, the first time I ever unlocked all the levels and difficulties as well. I'm never going back to the N64 versions of those.
What I would want from an N64 collection would be some stuff like Ogre Battle 64, F-Zero X with the expansion pak from the N64-DD, Excitebike 64, I'd probably give 1080 and Wave Race a go again. At least Sin and Punishment is on there. Although I bought that on my Wii ages ago...sigh.
That new N64 controller is making the SNES Classic with two controllers and 21 games look like a right bargain back then.
