Here's how I look at it. I've been wishing for a long time that Sega would make more of an effort to do re-releases of games from other platforms besides just the Genesis. The Sega Genesis is full of classics that deserve to be enjoyed by generations to come without a doubt, but Sega should also shine the spotlight on games from their other systems, including arcades, a little more often. This is just another step in the right direction, especially since all the arcade games included have never gotten a physical re-release in NA ever until now, not even as a bonus in another game like Shenmue or Sonic's Ultimate Genesis Collection. On top of that, the extras mean the games are in better condition than ever, even if they're limited by being on a handheld platform, but hey, it's better than putting these games on mobile platforms and making you deal with touch control.
I know there's always people who will be upset with anyone over anything they do, good or bad, but for the rest of us, this is a great deal. I've always been a big fan of Sega's 3D Classics and they're the first 3DS games I recommend to anyone. The extra exposure in stores at a budget price can only do right by them and I'll absolutely buy this singing all the way to the store and back.
