I agree, this will really be a shit show. It's especially scummy that just last week they announced a road map and opened pre orders only to now suddenly delay the whole game by 5 months(!). There's no way they didn't know about this last week, why open pre orders then? I know it says you can get a refund but it's not a good look to do it this way. Sports Interactive is so bad at marketing and timing things it's insane.
I think this delay will cause problems for both this game and the next one because they'll either have to focus on FM26 and undercook this one or they'll focus on this one and release a minor upgrade in FM26. There's no real solution anymore, all because of how they've done things.
