Oh, yes. In truth, the biggest reason I got a 3DS was the updated re-release of Devil Survivor. There are likely other 3DS games I'll buy at some point, but that was the big one.
I don't have my 3DS online yet, and I've probably got to change the name on it. It was used and I don't know the parental control code to reset the memory.
Unfortunately, I think I'm done with Plants Vs Zombies, as the minigames are starting to wear thin and I'm not repeating the adventure mode.
Also, Solatorobo: Red the Hunter was fun, and only annoyed me in about 2 chapters out of 20. (Maybe 3 chapters.) It's a lot of fun playing a game that has a sense of humor and that makes lifting and throwing your enemies around fun.
