Okay here is how it all went down way back then. Once upon a time there was a development team by the name of DMA. They created a little game called the Lemings. Way back in the N64 days Nintendo announced DMA as a part of their so called "Dream Team" of super developers to create games for the N64. DMA created Space Station Silicon Valley and Body Harvest for N64. They also created the top down driving/crime game called Grand Theft Auto for PC's and PSX. Later on during this generation of hardware they were bought out by Take Two when they created GTA 3 for PS2. They are now under the Rockstar brand name.
Now, about this baseball thing, it seems very interesting. I hope it works out for Nintendo so they can get a decent MLB game on the GCN and Revolution.
