If you're mainly a career player I can't comment much as it's not a mode i play. There are additional club formats in this version though.
In other vs AI modes the game is head and shoulders above DBC17. There is hardly an area of that play - dismissal variety, AI approach, crowd atmosphere, animation, that is not improved significantly.
On DBC 14 & 17, I pretty much spent 90-95% of my time on career mode to be honest, then usually played a few competitions with some of the classic international teams as the game's cycle came to an end. I've heard some positive stuff about the new game though, so I might call it a day on DBC 17 instead of carrying on with my career as I was planning.
Any idea when the PC version will be on its way? I've kind of stayed out of the build up for this one compared with the last two games, so I'm a bit out of the loop at the moment.
