astropup: PlayOnLinux is generally a nice tool. Now when I said that, I can criticize it. :P What I don't like about GOL is: outdated scripts, hdd space wasting and trying too much to automate everything. :)
I never use their scripts, I install games manually and only use PlayOnLinux as Wine manager for decoupling Wine prefixes for games from Wine versions and easier installations of games in those prefixes. Some extra space used for each Wine prefix doesn't bother me, I don't have thousands of games installed in Wine in order for it to become some concern and I have a 2 TB hard drive. That said, I look inside POL scripts once in a while, if some game installation doesn't go well.
I saw Lutris mentioned before, but I didn't really understand what it offers, besides being like a master manager for a bunch of emulators. Can you explain how exactly do you use it and what it's about?
