They should have stuck to their bread and butter which was CRPG. As soon as they ventured into more modern type fully 3d games they have been mediocre.
They have been struggling for a while. iffy games, lots of bad business deals.

trouble started with getting shafted by THQ and south park:stick of truth. THQ going bankrupt screwed them.
Famously didnt get a bonus for fallout:new vegas by missing metacritic by 1 point.
Obsidian has a deal with Inxile to share tech it seems. which might account for some of their design choices. avowed/clockwork empire sharing tech? its very odd obsidian didn't make a tactical game like Wasteland then..
Pillers 1 was kickstarted and at the time the most successful.
Avellone got rail roaded out of the company.
friends/in bed with doublefine. which should tell you alot. were part of FiG(so was inxile).
Tyranny didn't do well. unfinished game. with no ending.
poe2 was crowdfunded on fig. successful, but the game was not beloved.. not like Divinity: os1/2. or Pathfinder:kingmaker/wrath.
wait, Grounded was Obsidian? that was pretty well liked. uses unreal 4, so does outer worlds.
there was pentiment as well. which got no press at all.
Pillers was unity.
Avowed is unreal 5 it seems.
