BFF or Die did not have the pedigree to crack the top 10, but it solves a real gap on this list, local co-op for up to four players on a single PC without separate logins or online accounts. Rounds are short, the puzzle-and-defense hybrid keeps everyone doing something rather than watching one person solve it alone, and resets are fast. Nobody sits out for long. I would not build a whole LAN night around it. As a filler game between the bigger picks above, though, it earns its spot in the rotation, especially for groups still deciding who wants to lead.
