I haven't gotten to play yet, but, a couple of things I noticed just at a cursory glance when importing a league from OOTP5. Not sure if they have already been noted
1. The write-ups for each player are inaccurate. Some of my best players(Yogi Berra in his prime is one example), it says things like "platoon player at best". There were several instances of this. Didn't have much good to say about anybody.
2. Any pitcher in the majors or minors that is set to MR or CL before importing automatically gets a lower endurance than those set to SP before the import. Thus I have guys that were "E" SP's before the transition that have higher endurances than guys that were set as MR's but actually had "B" or "C" endurances as starters. That is messed up. Anyone who is importing their OOTP5 league would be foolish not to set all his pitchers that he can to "SP" or get screwed.
3. I imported a talent only league and much to my disappointment, can now see all the ratings of all the players. I realize I can go change the setting, but isn't it too late now? Everyone knows now what their ratings are.
It'll be a great game I'm sure, I'm really looking forward to all the new additions. Its just kind of funny that I only was able to look at it for 5-10 minutes and spotted 3 things this obvious.
