I'm not saying it's perfect by any means, but I thought this link provided some helpful information regarding different parking and transit options. I live in the city and have been to a number of games. I haven't found parking difficult. Personally, I find the lack of available ridesharing services to be more of a pain. I live too far to walk to the Canal District, but close enough that an Uber or Lyft would be comparable to parking costs. I can never reliably depend on drivers to be available and have found myself stranded at the end of a night so now I just drive and pay to park.
