I’ve finally beat Tales of the Abyss and decked out at 47 hours. That being said I did a fair amount of the sidequests that could probably knock off a good 3 hours or so. As an RPG it’s really great and I love the Tales battle system is one of the most engaging. It’s SSB in how you fight with your characters and each character has their strengths. Out of the 6 playable characters, (one special guest notwithstanding) you’ll probably only play as three since they are the fighters. You can easily command your spellcasters and healers from the touchscreen so there isn’t much need to play as them.
In terms of some of the mechanics there are some things that bothered me. This will mostly be comparable to other Tales games because they do some of these mechanics much more fluidly. Abyss as a Tales game is different for the sake of being different. The main one being the Field of Fonons or FoF’s as part of the combat system. Essentially using certain elemental attacks can create an elemental field on the battle area for a few seconds, certain other attacks can change completely when in the correct FoF but it’s mostly experimenting with knowing what works (or using a guide). The easiest strategies can often be have the spellcaster cast the elemental spell the boss is weak to (if any), and then proceed to use a tech from you character that creates a FoF attack as well. The problem being that any FoF attack does a camera zoom in. The skills in the game which can give you things from “jump in midair” to “faster backstep” are also decided by something called Capacity Cores which help you level up stats, sort of like EV’s in a way. Using the C-Cores to level up certain combinations of stats get you complimenting skills, but it’s never clear what raising your attack will give compared to raising your agility. Also the Overlimit system in this game is completely broken in every possible way. Overlimit is essentially a meter that builds up and gives characters a super mode and allows them to use a Mystic Art which is arguably their best move. In other Tales games such as Vesperia and Graces this meter is shared by everyone. In Abyss each character has one. If you know a boss is coming up have everyone charge it up (really easy compared to Vesperia, or heck Graces where you don’t hold charges in boss battles), then activate the Overlimit for each character one by one, you’ll probably knock a huge portion of the bosses health away within the first two minutes, and your sword fighters will probably be able to both charge it up again.
One last complaint is the side-quests because there are a lot and most of them can be missed very easily. There is a (relatively) spoiler-free guide out there to assist with doing them all but you can miss some really useful weapons and attacks if you don’t do these random quests at some points. In terms of the Tales series it is almost as bad as Vesperia where you can miss collector books because you didn’t look in a drawer at the start of the game.
Aside from those grievances I do hold Tales games in high regard because the plots can start simple enough but by Act 2 things start spiraling out of control. If Sticker Star just wasn't the RPG you wanted for the 3DS try this one out.
