My problem with gog, at least when downloading through heroic is that the download speeds as wildly slow.

Sometimes I have the same game on epic and gog, but the gog game will take hours longer to download compared to getting it from epic servers.

I think it’s because of my region. (South east Asia)

Additionally, they do not have regional pricing for the country where I live, so everything is much more expensive than it is on Steam.

So, once they offer regional pricing, I’ll switch over, even with slower download speeds.
