Pppsh, playing Mario first... I bolted to Ninja Gaiden, Double Dragon 2, and then eventually Super Mario 2.
Didn't Mario 2 have alternating 2P originally? We're playing alternating on it, but I thought we were able to play each with a personal controller, with our own progression, originally...
...Anywho, I haven't played Ninja Gaiden 1 in basically FOREVER. I'm actually surprised "NES HARD" isn't as daunting as I'd like to remember. Unlike classic Atari or arcade complications, things like Double Dragon 2 and even NG seem like they have smart difficulty. Galaga feels a lot like the Arcade ports on other systems (solid conversion!), Gradius feels incredibly solid (I don't think I've ever officially owned an original Gradius?), and flashing sprites don't bother me, even this many years later, lol.
I still think DD2 feels better than some indie BEUs, heh. Some things feel oddly super precise, sure (getting POWER KNEE! after a jump, for example), but I love how well they place context into a wide variety of moves, only executed with 2 buttons. While-rising Uppercuts, turning mid-jump to kick people in the back of the head, turning and hitting with the back-kick to cause double-over for hair-grab throws, which actually has 3 options out of the grab itself, spin-kicking enemies JUST as they jump out of a helicopter of from a drop... the rhythm still feels familiar, even after all this time.
Also, Bubble Bobble runs better than I'd expect, lol. I never played the NES version, and I'm surprised what I'm able to do without making the entire thing choke itself to death.
It's just nice having something like this without any disappointment. The Neo Geo system from a few years ago was plagued with errors and issues, those Genesis and Atari Flashbacks are work pretty poorly in comparison to original hardware, the controllers feel shoddy... this thing just feels perfect.
I hope all those who got one get to enjoy it as much I am mine!
And I hope they get easier to get as time goes on.
