Lutris 0.5.5 got sponsored and is in NEW since 3 weeks: https://ftp-master.debian.org/new/lutris_0.5.5-1.html
I also packed 0.5.6 since then, which is on Mentors: https://mentors.debian.net/package/lutris One of the reason why it's so long in NEW is probably the license situation. Some of the icons use the "Flaticon" license, for which it isn't exactly clear weather it's DFSG compliant (probably not).
