.. why GoG still doesn't have the current patch version and (expandable or linked) patch notes on the store page. For many games (e.g. No Man's Sky) the patch version and current game state has direct influence over my choice to purchase so I get frustrated at having to constantly switch over to the community forums to find out the most current information.
It's small features like this which are still missing which keep me from been able to convert many of my friends.
