It's buggy. Very buggy, some amusing, others not so much. The good thing is that the most glaring bugs are already known to the team and worked on. When everything works, it is great and I do not regret my pledge.
I have spent 3 hours with the beta, and I am having a lot of fun when everything works. The rtwp combat is really fun. I feel that everything is easy to understand, with good descriptions on abilities, spells and stats. Background look great, even if I was hoping for less static ones.
The combat felt a bit hectic at first, as it felt that it was going way faster than it should. After a few encounters, I do feel at home though.
I'm only playing on normal and that is how I intend to play the btea until the end. I have been wiped once by some specters, but I don't think i was supposed to go in there yet. So far, it has felt to me that all characters have been useful in combat. The rogue is the one that loses stamina the fastest if you are not careful.
I have been playing a monk and created a custom chanter at the inn. The monk and the fighter go in for melee combat, the rogue comes in afterwards. I found ranged weapons for my chanter and priest, so the buff, debuff and attack from afar. The mage unleashes spells like a madman. There is no room for complacency, one wrong move and you can expect a party wipe. Comat is still an area that needs improvement, like better pathing and auto-attack. Both known issues.
Writing is good, but it's mostly just side content, so one can't really comment on story. The companions don't speak, as they are just randoms.
Spell effects look nice, and music is decent.
