Despite a great pitcher / batter interface and deep sim features, MLB Power Pros has some glaring faults that derail it.
Anyways, I won't get into too much crazy specifics, as you can get most of that from the main Gamespot review. I'll just break down what I've liked and what I haven't liked... In case anyone out there is still looking for a decent MLB game on the Wii.
The Good: Surprisingly deep sim / general manager features that you can easily drop endless hours into, complete with built-in tutorial from a CPU "assistant". The pitcher / batter interface is top notch and never seems to grow old. Games against the lower quality teams tend to be easy, games against the better teams are more difficult... that might seem obvious, but respectable AI balance is something that few sports games can pull off. Power Pros is hardly perfect in this regard, games are still slanted towards offense... but overall things are nicely balanced right out of the gate.
The Bad: This game was designed around PS2 / conventional gamepad. Using the Wii Remote + Nunchuk is workable but not really ideal. (NOTE: The game can use the classic controller, but I don't own one of those yet). Baserunning especially seems needlessly complex when mapped to various combinations of d-pad + analog stick. I'm sure things are more intuitive when you have more face and shoulder buttons to work with. The shoe-horning of the controls from standard gamepad to Wii setup is minor in the big picture.
The major issue with the game is the fielding. The game does a horrid job of choosing which fielder should make the play... resulting in many infield hits and/or weak pop-ups dropping in. This frustration crops up every game without fail... and it's a major problem considering this was something that was worked out on NES games from 20 years ago. In addition, the fielding circle that you have to stand in to make a play is ludicrously small... which means that there is no such thing as a routine fly. It's a constant battle of tweaking to make sure you are perfectly aligned. Watching fly balls that appear to hit your player directly in the head, only to see them ruled as base hits is a major point of aggravation. Also, the fielders are far too slow in relation to the size of the ballparks. Even fast outfielders don't seem to have any range to catch up to high fly balls to the warning track or the corners... if it's not hit directly at them, it's dropping in. All of this leads to the aforementioned offensive-slant the game has. It's not that pitchers are weak or hitters are overpowering... it's that the fielders can't get to enough routine stuff to make plays.
Overall, I have found myself enjoying the game and have probably averaged about 4-5 hours per week over the last month. I'm about 35-40 games into my season... and the sub-par fielding can be glossed over when considering that the pitcher/batter interface and general manager features are so much fun to keep revisiting. I'd still recommend this one as a used / bargain bin purchase... and I'm sure playing it with the classic gamepad would get rid of some of the goofiness with the wii remote + nunchuk control scheme.
