I think I bought Harball 3, then got Tony Larussa Ultimate Baseball 2 or whichever one came out at the same time as HB3 anyways.

I helped test the FPS: Baseball games so I had a natural bias towards those games, and played the latest incarnation of that up until Windows XP wouldn't let me anymore. I tried the Miller Associates Baseball game, which was my first text based game, and loved some of the things that I could do with it, but wished I could do "career" modes or fictional modes ala the FPS series. I tried the High Heat Series, then the Microsoft Baseball. Doing a web search I came across a thread where someone was working on a "league converter" from FPS to OOTP4, so I bought it. The converter never arrived obviously, but so much time had passed since I'd been able to play my FPS league, I'd just start over. I was very pleased with 4, I enjoyed the changes in 5, and am really looking forward to 6.
