Released exclusively in Brazil by the legendary Tectoy, '20 em 1' stands as a fascinating testament to the Sega Master System's incredible longevity in the South American market. This compilation was specifically designed to provide immediate value for new console owners, particularly those purchasing the Master System III Compact. Rather than featuring high-budget late-generation hits, the cartridge serves as a curated museum of early 8-bit experiences, many of which trace their lineage directly back to the SG-1000 or the very first wave of Master System software from the mid-1980s.
The game selection is diverse but undeniably primitive, ranging from the famous 'Snail Maze' to sports titles like 'Great Soccer' and arcade-style diversions like 'Asteroids' and 'Safari Hunt.' While the quantity of twenty games is impressive on paper, the individual quality varies significantly, as most titles lack the graphical polish or mechanical depth found in standalone cartridges from the console's peak years. The interface is a straightforward, functional menu that allows for quick swapping between games, making it a decent "pick up and play" option for enthusiasts interested in the roots of Sega’s software library.
From a technical standpoint, '20 em 1' is a quintessential piece of regional gaming history that never officially graced shelves in North America, Europe, or Asia. It highlights the unique economic ecosystem where Tectoy thrived by repurposing older code to keep the Master System relevant and affordable long after the 16-bit era had taken over elsewhere. While it may not provide the technical showcase of games like 'Sonic the Hedgehog' or 'Phantasy Star,' its status as a Brazilian regional exclusive makes it a high-priority target for collectors aiming to complete a comprehensive global Sega collection.
