Balancing is terrible, always is in D&D adaptations but this is really bad. Combat is insanely slow-paced, this is how turn-based combat worked in the late 80s / early 90s. Add in the dice-rolling animations and it's a snorefest. Not much variation to character appearance and many races didn't translate properly, nor have they in any game since TSR sold out. No alignment system. Controls are over-inflated making the game feel very tedious right out the gate. First impressions instantly made me feel like the game was designed around the assumption you've played Larian's other games before. The switch between characters talking and "The Narrator" is annoying. Z-axis climbing and jumping over terrain in a top-down game is super lame, no fog of war (effectively you can see everything as if there are no walls between rooms). No edittable .ini or .cfg files for quick modification of features or removal or annoyances. Absolutely hate the soundtrack. Also, there is a Larian Launcher program you have to waste time bypassing.
If this is your first Bethesda game you might get caught up in the magic of an open-world. Morrowind was a fun but technically flawed game that put Bethesda on the map. Oblivion was a dumbed down version of Morrowind with a slightly improved graphics engine. By selling out to console design Oblivion was more successful in sales than Morrowind. It was a less fun game in every way especially with all the magic nerfs. Unfortunately, they continued this design strategy to the point Skyrim is like "RPGs for Dummies". If you do purchase this just get the Special Edition. The additional fan created content in the Anniversary Edition is absolutely terrible and was a nightmare to complete.
Decent graphics for the time with solid animations. Real voice actors who have a ton of experience with their characters. Outside of that things fall apart. 90% of the game content is finding trash objects laying around the map and solving pointless riddles in which the solution is generally just choosing the right contraption to shoot at it. Most DC fans already know the story so there's no surprises. The world is very small and it only takes a few hours to realize it. The combo attack system is janky, you'll either love it or hate it.
Decent graphics and animations for the era that capture the Batman feel. Talented voice actors who have been playing their characters for years. I have nothing else good to say about the game. You will either love the combat or absolutely loathe it as much as I do. They weren't kidding about the short (11hr) playthru time. There are dozens of better stealth games out there. Had I paid more than $4 for this I would have been upset.
Number inflation that completely breaks their combat system, worthless spells, and a ridiculous double-handed control scheme that makes swapping spells/weapons a nightmare. Terrible story with even worse characters. The voice acting could not have been worse. I was expecting improvements over Oblivion, this was a huge step-backwards. Sadly, Morrowind was a deeply flawed game but still their best product to date.
