as a non bioware game that didn't tout itself as an rpg...
I'd rate it average/worth playing through once for sure.
now AS a bioware rpg that is the third game in a series that started out as a spiritual successor to 90's crpg's?
hahaha, no. the game is disappointing in quite a few ways.
bioware's usual depth and polish, which is in their characters and story (not so much story, but it's usually filled with enough details to satisfy your thirst.) is nowhere near what it should be, as mentioned lots of arcs just POOF! vanish or you get little to no details or background on lots of events/characters, which is a shame really, because on the surface there are quite a few different elements in the game that I didn't mind, they just never went deep enough with them or did anything interesting with it.
now the gameplay has ALOT of different small issues, but with the clear lack (hell, knowing EA they are probably actively trying to avoid making it a possibility) of modding support, it'll be a cold day in hell before these things get fixed, and the sad thing is, they would be fixed within weeks if bioware had extended any sort of olive branch...hell look at skyrim, there are tons of UI/gameplay changes that were modded/fixed within the first week or two, and if anything it helped sales knowing that those things could be fixed easily.
I've only put in probably 12-14 hours (origin says 20, but I'm pretty sure there were quite a few times where I left it sitting there while I went and did chores around the house while the games war room tasks were running) so I know I haven't fully beaten the game, but from what I've seen, the game stays consistent with alot of the issues I have with it.
Oh and as someone mentioned, getting conversations to work sometimes is a fucking pain in the ass, they'll just stand there mumbling like a crazy person and the dialogue wheel doesn't pop up... I usually have to go fast travel or something to get it fixed, going into the menu or trying to talk to someone else doesn't fix it.
With how long the development time was, this game really feels like a letdown...they put way too much open world/MMO style side quests into it, and everything else suffered which was what most people were buying bioware games for in the first place.
