I just picked up a master system and do not have a single game to play! What are some good titles? I know about US releases for the most part but I hear the master system has no region lockout and European and Brazilian games will work? Is this true? I have heard that more titles were released in Europe, and especially Brazil where the system flourished up until the late 90s! So, what are some good titles from each region? how rare are some titles? Thanks!
