Arknights will have a collab with Dungeon Meshi and Sanrio

Recently, Arknights announced a collab with Dungeon Meshi and Sanrio, and as a fan of both, I was absolutely thrilled! The program also showcased the character illustrations for the collab, and my anticipation is through  roof! Game collabs are increasingly common. For instance, Reverse:1999 recently announced a collaboration with Pizza Hut. So, which game collabs have deepest impression on you or are you most looking forward to, and why?
