All subjective opinion. I consider Obsidian to be the best RPG studio bar none. And their most recent big RPG, Grounded, has sold over 10 million. CP2077, despite an orchestrated campaign against it, sold 15 million in its first month out. Witcher 4, Dragon Age 4, Starfield, and even Avowed will all sell 10 million plus. Given this is the Larian forum, it makes sense which studio will be the most popular here. But there are a lot of other gamers out there beyond this forum <shrug>.
