Well you're discussing overlapping universes, which involve video games and television shows, so I'm asking to what extent that crossover extends. In my previous example, I referenced Half-Life, Minecraft, HALO, Metal Gear Solid, Ratchet and Clank and Gears of War. Am I constrained to one universe with the ability to interact with many, or can I be a mix of multiple universes and exist in only the Minecraft one?

This series will take place in that one Minecraft world. Characters can come from any universe and I'd prefer if they be canon, but OCs may be used. However, I don't understand what you mean by that last sentence.
