Action PC Baseball
I think my favorite sports simulator of all time is Action PC Baseball. Of all the (worthy) baseball sims I’ve tried, this hits the “just right” level of simplicity and depth. Instead of being a “tycoon” game, it’s a single season replay/simulator that requires a lot of manual setup. It’s also an individual game simulation that’s pretty easy and relaxing to play, with a game able to be finished in minutes with the right settings.
This seems like Jekyll and Hyde, but these elements actually complement each other well. If I’m in the mood for some relaxing time-passing, I can just fire up a single game controlling both teams and enjoy it for that. If I have the time and energy for creating massive “what-ifs”, I can focus on building the rosters (which is frequently very fun). Though simple and a little hard to get into, the UI is very smooth once figured out.
In short, this simulator is one that has given me many, many hours of fun, and different varieties no less.
