I’ve gotten through season 1 of OOTP 15.
Fundamentally, it’s the same game for me as OOTP 14. I don’t really like 3D mode all that much, so I’m not using it. I turned on all of the foreign leagues because they’re awesome, but they really slow down simulating games, and I might just turn them off again. I also saw that the AI is a bit smarter—you can’t flip players quite as much as before, and the game doesn’t over-value setup men—but I still made what I consider to be major steals with some regularity. On the plus side, they’ll consider debt-for-debt swaps: I have $13 million tied up in Dan Uggla; to get rid of him, I had to trade some guys of value an take on a similar guy with a big contract but maybe some more upside. In prior editions, the game would freak out because of Uggla’s contract and I’d pretty much have to eat it.
I will say two things have improved greatly: first, I love the fact that I can get ratings normalized across the entire league, rather than by league and position. I like seeing that the 75-potential second baseman is really more like a 50-potential guy in the league; it’s just that second basemen are so rare that 50′s the best you can do. [Not really with second basemen in the current MLB; actually, that's more like starting pitchers, where a #1 starter can be a 60.] Second, the widescreen-friendly interface is nice.
But given that OOTP was such a fun game last year, it’s getting hard to improve.
