Minuteworld: do not remove the neptunia games. if you do, that is anti consumer. I just bought the first one and plan on buying the others. I know they don't get updates which is why you should demand idea factory to update their game on your platform instead of removing it outright. I don't care about other games that get no updates gettingt removed but if you remove the neptunia games, I'll just go fuck gog and deal with steam and scene groups.
I have 118 games on this site. removing shit people wanna buy regardless if its up to date is anti consumer.
I don't think the Neptunia games will go away. But why not buy them all now? They're all 50% and (IMO) not very expensive. Note that they will stay in your library even if they were ever removed from the store. To be really sure you can just download and backup the offline installers.DRM-free ftw!
Also, I hate to disappoint you - 118 is not really much. I have about 750 and learned only recently (when all the profiles were public... shame on you GOG), that there are many people with more than the double amount...
