For me, it's a big step (back) in the right direction. It feels more like a finished product than 26 was. Still not the best opus, but the terrible years might be behind us!
I can't say how or why exactly, but FM26 was the first FM in 15 years where I had absolutely no sense of immersion. FM27, I did find myself having a hard time stepping away from my laptop. And think about my team's story. So somehow, the immersion is back, even if the game is pretty similar.
It might have something to do with all the removed bugs and the awful pop-up UI system. There will always be things missing, it's still only a simulation game, but at least - for me - the immersion is back!
