Before you order R-Type Command, learn about the Dobkeratops in R-Types. The PlayStation One game is a history lesson, or better explained as a bundle of R-Type I and II. Sony put R-Types on the PlayStation Store as part of their classics collection as a 243 MB digital download. The re-release will work on the PlayStation 3 and PSP.
Following R-Types is the Eye of Judgment: Biolith Rebellion 2, an expansion pack with 100 new cards to collect. Since Gamestop is already selling the physical cards produced by the Wizards of the Coast Sony put the $14.99 expansion pack online too.
