If I understand this correctly, you value Steam's honesty over a few instances in which GOG hypocritically violated their own DRM policy. That sucks, for sure, and GOG should be called out for it -- but at the end of the day, the vast majority of games in my GOG library can be downloaded as offline installers that don't need to contact a server, while the vast majority of the games I own on Steam can't (barring, of course, circumventing Steam's fairly weak DRM scheme, which is illegal).
I don't follow the logic here. You said it yourself -- GoG has only allowed DRM onto their platform four times. This is a violation of their anti-DRM policy but it still means like 99% of games on GoG have no DRM. It's good to be principled about these things but I don't see how this merits a knee-jerk response to run to Steam (a platform where 99% of games do have DRM and no guarantee other than an informal promise that they'll do "something" to make their games available if Steam were to shut down).
Ares has a N64 core that's mostly homegrown (not based on any existing emulator like Mupen) and has a lot of promise. It's actually probably already the best N64 emulator, but I don't think many people know that.
