A review of newly unveiled plans for two competing casino projects in Springfield has found many similarities, such as their generation of jobs and commitment to diversity, but also many unique ideas on how each company plans to deal with issues ranging from public safety to economic development.

MGM Resorts International, planning a casino project in the South End, and Penn National Gaming, proposing a casino in the North End of the downtown district, filed their formal plans by Jan. 3, the deadline set by the city. The hundreds of pages, including supporting documents and reports, are now under review by two mayor-appointed review committees and the city’s hired consultant, Shefsky & Froelich of Chicago.
