Larian Studios isn’t working on full-fledged Baldur’s Gate 3 DLC, but there are at least more evil endings on the way – and founder Swen Vincke says “they’re really evil.”
Evil is hard to pull off well, very few games manage to make evil playthroughs actually interesting. A lot of the time it just means more slaughter, which in turn means less content since you kill off so many potential quest givers and followers. Plus, a lot of "evil answers" in dialogue often just means being an asshole to people, which usually closes potential content avenues. And while that is sort of realistic (people don't want to work with you if you're an ass to them) it's not really that satisfying.
Evil options and evil endings should probably give you more opportunities to make more money, gain more power, so in-turn make the game easier in some ways. Because in the real world, you have to be evil to gain money and power.
Rather than becoming a criminal in an evil run, maybe you just become a capitalist. /Semi-sarcasm
Tyranny is a small but excellent game in that regard. You already start as a lackey (more like a prosecutor) for a tyrant that takes over the game world but a tiny bit of a peninsula housing a few different but unyielding factions. You read the tyrant's edicts and bring about literal disasters like earthquakes, storms and eruptions at the very start of the game, then you can choose whether to continue in compliance, thwart tyrant's generals to your side and rebel, go anarchy route and impose your own will on both the tyrant's armies and the local factions, etc.
Imo one of the rare and true Fallout 1-2 and cRPG followups in the last decade, with a proper flavor of evil.
Tyranny's magic creation system is so simple yet powerful that it amazes me how there aren't many games at least copying it. It can even be improved upon, or simply made more complex and more powerful, but even in this form it is an excellent implementation of magic compared to find-new-magic-words or use-perk-points-to-unlock-and-upgrade-magic types of implementations.
