I started Shin Megami Tensei IV at around the same time I got my 3DS back in October, and I've been playing on and off since then. However, I'm finally at the trailhead to the last dungeon, and I had been consulting a guide because I had landed the Neutral Ending by chance (I heard it's a more uncommon occurrence than Law or Chaos) and I wanted to know how much longer I had.
I also started Tales of the Abyss, Super Mario 3D Land, and Luigi's Mansion: Dark Moon over the past few weeks. Been juggling those as well, even though my focus has been mostly on completing SMT4.
I have to say, aside from Abyss being a good Tales game so far (Luke's annoying ass notwithstanding), the 3D is pretty disappointing. I didn't buy my 3DS for the 3D thinking it was a gimmick, but it turned out to be something pretty cool that I could appreciate if they did it in a fun or interesting way (SMT4 is beautiful in 3D, makes 2D feel pretty lacking when I turn it off). 3D Land and LM2 have great 3D, as well, and so do a good number of games. Seems kind of a waste, but it's my only big complaint about Abyss so far.
I'll probably use my completing SMT4 as an excuse to start 20 other games. I don't do very good with just focusing on one game at a time. :/
