My overall pick is to take Sammy Sosa's version. This game is great fun and is way closer to resembling a real softball game than the TPS version. I do DEFINITELY recommend getting the Microsoft Sidewinder Gamepad (around $20) for this game as you can use all of the buttons available rather than using the keyboard. The gamepad makes a huge difference in gameplay !
Sammy Sosa Softball Slam
HIGHS ----- 1/1 count optional control pitch location align outfielders and have a short fielder change player appearance and type pitcher/batter interface close to real life batter can slide up to hit the ball can swing high, reg, low wind effects the flight of the ball 4 or 8 team tourney 6 different very unique fields day/night games 2 different batter views, high and low ability to hit where you want (backside, etc) has a family mode for kids mens teams, womens teams, co-rec errors can be turned on or off players use either an aluminum or wood bat wacky announcer good graphics game has speed settings, next batter comes up quick, dont have to wait on runner to run out HR, etc LOWS ------ no regular season uniforms aren't the way players look today all hr's go about the same distance can't turn off power throw when using low batter view - lose sight of the ball temp in a high arc pitch - which forces you to use the high view players always run and throw awkwardly (they did this intentionally) pitcher can't 'pump fake' wacky announcer gets old after awhile (you can turn it off) not a whole lot of appearance difference between night and day games big ball/player underscore on where ball is and who has the ball, would like to see it optional no way to save stats for an extended period of time
This game was lacking in many areas. The batter/pitcher interface where you need to start swinging way before you would in real life. You can hit a lot of HR's in a game, but that is upsetting as each HR is run out at a slow pace by the batter making for a long game. You cannot change the 'tempo' of the game like you can in Sammy Sosa.
TPS is a more serious attempt at a softball game. It has potential but without a solid grasp of the basics the game falls short. You can setup nice uniforms for your team and the HR's look great and it even lists the distance you hit them.
The game is cheap enough that if you want to give it a shot anyway, then go ahead, but I definitely recommend Sammy over TPS.
