Roblox is a very different kind of game company though. I've noticed the more service oriented game companies have better wages and work life balance. The more old school, content heavy ones have lowe pay and longer hours.
Ultimately it's working on game tech and companies like Roblox also hire for other roles that don't have exact equivalent in web or mobile development (art and game design roles mostly). Limiting your definition of "game development" to content heavy games with low pay and longer hours, especially when the industry is moving away from that type of game with a few exceptions, doesn't make sense.
