I find it rough playing versions before 24 now that positional play is finally a working mechanic in the game when it really should have been 10 years ago, but I'm still down.
I'm tentative on 25 given how slow progress is made on these games (They're generally amazing games, don't get me wrong) and I find it hard to believe they'll be able to convert to a whole new engine and deliver an equivalent or improved experience in just one year, but also I'm terribly addicted and will probably buy it as soon as the beta drops.
