Early BioWare stuff. Specifically KOTOR (don't know what's going on with that remake, but doesn't seem to be going anywhere right now), KOTOR II (yes, I know it's Obsidian, but still), and Jade Empire. Probably Dragon Age: Origins as well.
Since they're already doing it, it's probably a useless mention, but Splinter Cell needed it, especially for PC.
Star Wars: The Force Unleashed and the Kyle Katarn Jedi games could probably do with a touch-up as well. But they're "not canon", so that's not happening.
Maybe also the original Deus Ex and/or Thief.
I expect System Shock 2 might get one in a few years, although it isn't as desperately needed as the original was.
God forbid any exec there have literally any brains or sight above 3 months. I'm so goddamn frustrated with the shell corporation formally known as Bioware. Yes, your quarterly revenue is in the toilet, you invest money to make a killer game and make profit when you release. Games take time, stop fucking laying off people and trying to squeeze it for every dollar and just make a good goddamn game.
They have massive IPs like KOTOR, Mass Effect, and Dragon Age that literally everyone is chomping at the bit for. They could have staff working on all three with a new game coming out every two years with DLCs in between, but they're afraid to invest in it.
They could have the next RDR2 or Witcher - if they actually invested in it. They could be the name for RPGs again, but they're too afraid about not being able to afford their next BMW.
Unpopular opinion: They never were. And neither was Bethesda. Black Isle/Obsidian are the true masters of RPGs. There was a period of time when they would take other studios' engines and IPs and produce sequels/spin-offs that vastly surpassed the original in terms of writing and world design. Bioware made Baldur's Gate, Black Isle made Planescape: Torment. Bioware made Neverwinter Nights, Obsidian made NWN2. Bioware made KotOR, Obsidian made KotOR2. Bethesda made Fallout 3, Obsidian made Fallout: New Vegas. If anything, it's Black Isle/Obsidian games that deserve to be remastered.
I'm disheartened by dreadwolf. Talk about a game with 10+ years of hype building, the fanbase is incredibly loyal, most gamers know the franchise well enough to pick it up at launch, all it needs is stable investment from a studio. It was announced now 5 years ago, and we've had.... 1 behind the scenes video and another 30 second trailer but plenty of news of team issues and money issues.
To this day, I'm still salty about them scrapping the EU. I know I have totally zero effect on anything, but personally I absolutely refuse to acknowledge Disney's canon as "the" canon, no matter what those fuckers say.
The way I view it is all they did was give it the Zelda treatment: they didn't get rid of the EU in creating Disney lore, just split it off into a different timeline. In my mind there are now two canons: Legends canon and Disney canon. They're both canons, just two separate canons.
