So, I've gotten a bit farther. Difficulty has picked up, I've lost a couple times now (not that I'm playing particularly well or anything, but it's more than I can say of a lot of games these days.) Most of the systems have revealed themselves at this point I think, along with most of the cast. Characters are fairly varied; you get some interesting stuff like team buffing spells that you wouldn't see in this genre normally, and they don't all follow the DW formula of having a bunch of light, light, (repeat n times) heavy comboes. Some have ranged weapons, others combo in different ways, etc. The monster medal thing is actually pretty neat; you don't keep them between battles so they act as sort of resources you acquire by smashing enemies and then deploy to defend shit while you cover other parts of the battle. Also some medals are just 1 shot deals that do things like cast a spell or restore hp or mp. Enemy variety isn't shabby either, you get various spellcaster type enemies, enemies that can block, etc. The bosses are fairly interesting too, besides the lame first one. The character building systems are pretty simple but at least give you some options, like specializing in a particular special attack or stat or whatever. I'm nowhere close to filling out all the skills, I doubt it's possible even at the level cap, though you can probably get to like 70-80% or something. Then again, I dunno what the level cap is, might only be 30 or 50 or something. Equipment has room to be an incredible grindfest if you're into that, there's options for crafting with random bonuses so I'm sure you can imagine how out of hand that could get.
The actual combat is surprisingly good; you actually control a team of 4 characters, cycling between them. You also have an extra resource besides your tension (musou basically) which you use to cast spells/abilities. In musou mode you can cast those spells for free and when it ends you get a big finisher move that basically clearly your field of view. The lower level enemies don't pose much threat, but the stronger ones can be pretty annoying, especially in groups. Fighting multiple golems or killing machines at a time, for example, can be a pain. And even the little cunts can be a problem by way of status effects; silencing you or lowering your defense or whatever. The last set of resources you get are yggdrasil leaves (revive party members, you get too many of these imo) and healstones (these at least cost you money and only restore some hp.)
If anyone has a more specific question than 'is gud?' feel free to ask.
