Critic, I know you get a million recommendations a year, so I've always been very conservative with my game suggestions to you, only giving them if I think they're strongly warranted (less than 10, or maybe 5, games in the past 10 years). So, for that reason, I hope you'll give some strong consideration to the 3 listed below, all of which I've mentioned in the past.
North & South (NES): This is a genius action-strategy game (set during the Civil War, with a dose of modern humor) that truly must be played in order to comprehend its brilliance (read about it or watch Youtube videos, and you might be tricked into thinking its mediocre). By now you've played so many games, that you might think you've tried everything--but there is truly nothing else like North & South. Is it an A? I don't know... it might be or it might be a B. But, having a decent idea of your gaming tastes, I'm confident that this will be earning a decent grade and a "hidden gem" icon. It's the uniqueness of this game that is the main reason for me recommending it. It's hard to describe, so I provide this for more info:

Final Fantasy VII: I'm not recommending this based on the claim that it's the best RPG ever or anything like that. It deserved an A in the late 90s, but I hear that it hasn't aged well-- so maybe it's only a B or C now. Regardless, I recommend this game, because, of all the games that you haven't yet reviewed, in my opinion FF7 is the most glaring omission from the site. And, while I think 99% of RPG reviews could be done by an RPG Critic, Final Fantasy 7 is in the rare 1% category where I think your readers really would not only prefer, but need, your review. You wouldn't have let the Platformer Critic do your review of Super Mario Bros., would you?
Final Fantasy Tactics: Final Fantasy Tactics is in my top 2 games all-time (I can never decide between this and Panzer Dragoon Saga). IMO, it also has the best story of any game ever. But neither of those is why I recommend it. Normally you could pass on this game.
But, you gave Vandal Hearts an A+ and loved that game, so that's why I recommend this. FFT is the same style of game as Vandal Hearts, but FFT is almost universally considered a superior game.
