First off, I'd just throw out there that I never understood the "flop" of Jericho. It was incredibly fun with an amazong story and started me down the clive berker rabbit hole. But for forgotten games, I always bring up Titanfall 2. Easily the best shooter campaign I've ever played, but it wasn't COD or Battlefield so no one cared. It still has a dedicated community and multiplayer, with an awesome survival mode. Strongly recommended.
