I'm pretty sure it's only for Sony/PS Card members, I used mine right before xmas, worked fine.
Only other reason it may have failed was because the coupon had a limited number of uses (was stated in email).
Not exactly a deal, but XBLA has sent out some mailers as of late with "free gifts" included inside. Just a heads up so people don't toss them out; they all have codes for 480 free MS points inside. Happy gaming!
$79.99 on Newegg right now, no tax outside of CA, free shipping. Better deal imo.

I've been playing it since it released, and already have a season of My League completed as the batter. It's not bad, but the missions seem much harder to complete this time around. I think the slowdown issues that people are complaining about on the comments page should be fixed once they post 1.1.
Had tried posting this before but got no interest. Glad to see people taking the time to play a well-made game like this, it's by far the best text-based sports sim franchise I've played (since 2003). I think this is a prep to the 2010 edition coming out around the end of this month. Enjoy!
