Games unlikely to run, and unknown ones
These are the games where the evidence says it is unlikely, or we don't know yet. Treat the list as a guess: one bad report never decides a game, newer runtimes fix games every few weeks, and offline modes often work even when online play is blocked by anti-cheat.
The good news is on the Games page. How games are rated is explained under How we rate games.
