I like this game. Multiplayer is a lot of fun. I had an extra inning game in multiplayer today, lost 6-4. It's got simiple controls, but it's strategic in trying to figure out where to pitch and when and which type of swing to use, much like you'd see in other baseball games' pitcher/batter confrontation. It's also good how each field presents a different type of rules. A power hit to the right side in LA will be a hit, but in SF it would go in the water for an out. Also, it matters how you set your lineup. Everyone rotates position, so everyone pitches (unless your playing a 3 inning game where 3 of 4 players pitches). It starts out that the leadoff hitter pitches the 1st inning, 2nd hitter pitches the 2nd, and so on. I like to put a good pitcher up 3rd, so he can close out the game if it's a 3 inning game.
It pays to play tour mode offline a bit, in order to get some points to buy cards and unlock MLB players. Otherwise, you have 1 MLB player and 3 generic players who are each good in one category: power hitter, control pitcher, power pitcher, etc. I got more points in offline tour mode than i did playing online.
I hope this game catches on for more multiplayer games. I waited about 1 to 2 minutes today for a game. Not too bad, but could be better. For what it is (it's not a sim baseball game), it's fun. If you like baseball, chances are you'll like this.
