The ./play.it script is a better alternative to lutris in a couple ways:
_the game doesn’t crash even if the 32-bit version of libtxc-dxtn-s2tc0 is installed
Hasn't affected me yet, but would certainly be annoying.
_multiple languages are supported
Personally doesn't affect me since I prefer my games in English, but I can see how this would be nice for other people.
_movies are supported
I've noticed this doesn't work with the Lutris version indeed. That's a real shame.
_native packages are built, and can be kept to install them on multiple machines
I personally don't have multiple gaming systems in my house and also don't like to install .deb files locally.
_installation is done system-wide, avoiding unnecessary data duplication on multi-users systems
See previous argument about local package installation. Also, you can do a system-wide installation with Lutris in for example /usr/local/games/ by running it with sudo.
_you don’t need to install anything but the game itself to play
True, but I like Lutris to manage all the non-Steam games on my machine, kinda like Steam does.
By the way, I already contacted lutris team some time ago proposing to help them parse ./play.it scripts, and my offer to them is still open.
Sounds good, I'll see if I can get a hold of Strider and remind him of this. It would be nice to have things like the movies and localization working in Lutris as well. Whether you want to use Lutris or not is a personal preference obviously, but it would be nice to make the gaming experience as good as possible for everyone.
