I got into the beta for Galaxy 2.0 and I have to say, it is incredible and it's still only in beta. Sure, there might be bugs and some features still missing, but it's so comforting to have everything collected under one launcher. It's easy and simple to integrate your other accounts across Epic, Origin, Uplay, Battle.net, Steam, GOG itself, and even PSN or Xbox Live. The UI is fast and snappy, you can easily tag a game through a few clicks, almost all the games have beautiful artwork attached to them (icon & background) and it also tracks your playtime even though you're using a different launcher. It is without a doubt the best launcher I've ever used and once bug fixes and feature-sets are complete, I'll definitely just use that one to track and organize my library. It makes it a lot easier to track all your games, it gives a good overview of what you have, and you can easily sort and search it without much hassle. The other launchers are fast to launch and you don't really even notice that you're going through Origin or Uplay or whatever.

Background artwork for a game, works on all games no matter the launcher:
Then it gives you a nice option if you want to customize your game with different types of art:
Once this becomes a public release, I highly encourage anyone with multiple launchers to get on it - and it even works extremely well as a backlog/library organizer too!
