How many GB is Sigma World Online?

0.15 GB

That is less than the typical Role-playing (RPG) game, which needs about 6 GB.

Leave at least 6 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

Sigma World Online - is an online sandbox with a huge world from many star systems. Choose who to be: space explorer, miner, merchant, farmer, culinary specialist, scientist, builder or hunter, or build your empire.
