In games lore means the narrative or backstory. Basically worldbuilding, story-rich elements, the premise of what’s going on in the game & who are the characters, why they are on the journey etc.
More ambient music, something that would be immersive for the setting. That music was a bit distracting and didn’t seem to be chosen specifically for the game, but like a random track.
For story-driven game, ambient soundtrack is easier to handle because it helps to explore the environment and can also be a tool to hint on upcoming battles/enemies.
Yea, a menu to turn on/off sounds and music are always a great thing to have in the games. Even if I like the soundtrack, it can get repetitive, if you play a MMO for example. ambient sounds like weather or environment (steps etc) are different and help to immerse into the gameplay.
