I'm 40 hours into Tales of the Abyss, I'm thinking I'm probably getting near the end now. Overall the cast of characters has grown on me, Luke and Tear are a little mixed for me since they both have annoying moments; Anise, Guy, and Jade are all amazing and have consistently made me laugh, and Natalia is alright but kind of one dimensional. I've actually played almost the game entirely while using public transit to commute to work (a little bit was played while at the laundromat). I basically play around 30 minutes to an hour each day depending on if I play going both ways, it hasn't been too bad, although I play differently than I normally do when gaming at home since I have to make sure that I can get to a save point fairly quickly if I'm near where I have to get off (I kind of wish there was a quick save option, hopefully there isn't one that I don't know about, haha).
Oh ya, I wouldn't suggest turning on the 3D for Tales of the Abyss on the 3DS, the effect is noticeable, but it is also one of the most nauseating things I've ever tried to look at while playing an RPG game, haha. It's seemed especially bad when I was just running around a town.
