VGChartz's top five open world games - Results are in! Detailed results inside

[HoloDust]

1. Gothic
2. Gothic 2
3. Gothic 3
4. Might & Magic VI
5. Might & Magic VII

Fallout 1 and 2 are open worlds as well, and would be number 1 and 2 for me, but they are hub based, so not open world in modern "(mostly) seamless world" sense.
