Dragon Age: Origins and Dragon Age 2 are unlikely to get a trilogy remaster, according to former BioWare executive producer Mark Darrah, even though they originally planned a “Champion’s Edition” of the first 3 games— similar to Mass Effect's Legendary Edition.
“There’s basically no one outside of BioWare anymore that understands the Aurora engine. So unlike Mass Effect, which is Unreal… there are basically no companies that could help you.”
Overwatch was allowed to have more variety in designs when it was paid because they were selling the game and maybe loot boxes (since you could earn everything by playing)
Now they need to sell the character skins so every new hero design has to be super safe
