If you can look past the cartoon-ish graphics, you will be pleasantly surprised.
For starters, the batting controls are amazingly accurate and in-tune with the yellow target they give you. If you hit the ball on the top of the circle, you'll pop it up, and vice versa for the bottom. Pitching is very nice, and it makes you learn your entire bullpen, seeing how strong each pitch is for each pitcher, and aiming the pitch for how much break your current hurler can utilize. Fielding is natural; however, it is here that I have my one issue with the game. It is a little off accuracy as to how fast players can get to first base on a ground ball. Turning double plays is much harder than it should be, and for some reason, I wasn't able to throw out Jim Thome when he hit a soft ground ball to third base; anyone who knows Jim Thome would know that my grandmother could throw him out on that play. Other than that, though, the controls are simple enough that anyone can learn them, but still leave enough advanced enough for those of us who know a bit more about the subtle nuances of the game to be able to do more.
Season mode provides an amazing amount of detail for the player to be able to control. Every player can be set up to do their own individualized training, to work on their own weaknesses, and if players work on the same things, they can become closer friends and work better together. Also, you have a point system that works as your team funding, and you have to balance playing well to earn points against paying the players' salaries in daily increments and shopping for tools to improve training. Also, as in real life, trading does not happen in one day. If you offer a trade to another club, they are given 5 days to consider the trade and get back to you. That's a nice feature, as it gives you more of a realistic feel to the trading game, for you never really know what day out of those five that are given when they will get back to you. I'm still early into this mode, so I continue to look forward to seeing where the season will take me.
Success mode is my favorite feature that I have ever seen in a baseball game. It gives you a very RPG-ish kind of feel, where you start out in college as a very poor player, and have to work and train to become good enough to be drafted to the pros. However, it can't be all training for the game; you still have class to study for, girls to date, and work for money to buy items to make you a better player. Before you start with the "I don't need to buy more items, dating isn't important, and who needs to study when you just go to the pros", I can state that most of that is partly true, but if you don't study you'll fail your college finals and be kicked out of school (game over), and the equipment you buy is a great help to you. I never did go on a date, but I'm sure that helps too. :) One of the best things about success mode is that the events that happen are entirely random, giving you endless replay value; there were times I restarted a section because I hit the wrong key, and the re-loaded game had different events for the same timeframe. Also, the fate cards are a nice touch; it's a game of luck to have the right decision to make, and if you don't, you are forced to just pick the best bad choice. All in all, Success mode really made me feel that when I got drafted, it was really ME, not just a created player I plugged into the roster.
In conclusion, aside from a small fielding bump in the road, MLB Power Pros is a smooth ride from starting pitch until they call in the closer. Any baseball fan would do well by giving this game a shot.
