This probably isn't too obscure of a game and I'm really sorry for it being another Sonic game, but I feel the need to stress.
Sonic Chronicles The Dark Brotherhood has to be the biggest rush job of an RPG I've ever played. Sound effects and music are incredibly stock, the battle system is a poor mix of Mario & Luigi with Elite Beat Agents, every 3d model in the game looks like utter garbage, the story is pretty stale and dull and over all it's just a half *** attempt to make a beginners first RPG.
Like I think it makes Sticker Star look like Final Fantasy 6 compared to this game in my opinion.
While it is a pretty ****ty, obscure game, there are Sonic games that are way worse like Sonic Labyrinth, Sonic 06, Sonic Spinball, Sonic R (Sonic R is worse then Sonic 06 but not as bad as Labyrinth).
Also, interesting fact: Sonic Chronicles The Dark Brotherhood was made by Bioware...yep. One of the best RPG developers of all time made one of the worst RPGs ever. It's clear they didn't want to work on the game considering the overall quality of the product. Bioware normally does this for their games:
Make it look great (Based on technology at the time)
Good, beautiful music
Great, dramatic story
Good User Interface and Controls
Reasonable Difficulty (Except in Mass Effect where it's borderline unbeatable)
Good cutscenes
Non-Linearity
Decisions alter the game
Sonic Chronicles however was their ******* child they weren't proud of:
Bad music
Stale as **** story with no good drama
Bad Controls
Too easy
Horrible cutscenes
More linear then Final Fantasy 13 (I'm serious here)
Decisions are just an illusion to make idiots feel like they're doing something
Seriously, it is crystal clear that Bioware didn't want to make this game, no matter how much Yen/$$$ was thrown at them by Sega. I'm just glad EA bought Bioware after this disaster to prevent a Sonic Chronicles 2 being made, for once EA was the good guy.
