My problem with GOG is that every time I buy a game on GOG, something then happens to result in me having to buy it again on steam. Once it was that the GoG version lagged too far behind, several times it's been that workshop support has been added, or in one case, workshop became the only source for moding.
For that I'm unlikely ever to buy from them again
Why wouldn't they just say 'la poste electronique' like a normal person?
