Question about the gameplay from someone new to this type game.

Everything is so well done. The atmosphere the writing the acting.

But it’s my first turn based game of this style and I have a question. So far it all seems very on rails. Like the path through the game and even the weapons I find. Even the encounters all seem to be roughly the same difficulty as though the game knows what my level characters will be at for each encounter. Is this true and is it common for a game like this?

This isn’t a criticism exactly. I’m just not sure if I’m understanding the games potential fully.
