Grim Fandango,
Tales of Monkey Island,
Dead Space,
Red Faction Geurilla.
All awesome, all massively underrated or unknown.
Dude, none of those are unknown
or underrated.
Anyway, I would say...
King's Bounty (1990, PC/GEN)
-- Fun antecedent to Heroes of Might and Magic; no less satisfying than its sequels
Final Zone (1990, GEN)
-- Heroically twitchy mech game; features some of the best graphics on the Genesis
Shadow Warrior (1997, PC)
-- It was obvious that the Duke3D engine was on the wrong side of history by 1997, but that didn't stop this game from making admirable aesthetic choices, employing ethnic stereotypes and kicking ass all the while -- if you liked Duke Nukem 3D (and who doesn't?), you'll appreciate the even more adventurous level designs in this, such as canyons that float in the sky à la Avatar.
Doom 64 (1997, N64)
-- Bookended as it was by the N64's major launch/early titles (Super Mario 64, Mario Kart 64) and GoldenEye 007, it never attracted much attention, but Doom 64 is still in a word, well, badass -- Midway's level designs are challenging without being grotesquely difficult (except the bonus levels -- those are nearly impossible, yet infinitely rewarding), the graphics are executed crisply, transitioning Doom into real-3D, and the game runs at a solid FPS clip. If you bought Super Mario 64, this was the next best thing on the N64 market in March of '97.
Blast Corps. (1997, N64)
-- For fans of unfettered destruction, this delivers and then some -- is arguably Rare's finest hour
Star Wars: Jedi Knight: Dark Forces II (1997, PC)
-- While acclaimed at its release, this shooter has since fallen out of the public eye -- a shame, since for its moral decision-making, force powers, melee combat, and inventive level designs it's every bit as ahead of its time as GoldenEye or Half-Life
Mystical Ninja Starring Goemon (1998, N64)
-- While only a B+ as 3D platforming goes, the game's anachronisms and surreal humour make it a winner
Dragon Warrior Monsters (1998, GBC)
-- Second only to Pokémon as monster-raising games go, this game's plethora of features -- it has randomly-generated maps and 46,000 breeding combinations, for example (I bred together a talking tree and a bat and got a stump with wings) -- caused me to quit playing my PSX copy of Chrono Trigger on a first run-through altogether once I began to get into it
Turok: Rage Wars (1999, N64)
-- Of all the Turok games, this is without a doubt the best, as it gets rid of what was
bad about consensus series' highpoint Turok 2 -- the overlong, tedious levels -- and replaces it with uninhibited adrenaline; making it a worthwhile console competitor to tournament shooters such as Q3 Arena and Unreal Tournament
True Love (1999, PC)
-- The King of Bishōjo Dating Sims, and why not? True Love replaces the game-as-cut-scene concept so often employed in its genre with an engaging system of personal micromanagement (you have to upkeep your grades, health, etc. -- a bit like The Sims), and replaces rote sexual sensationalism with, at its best, well-developed characters. Plus, it lampoons FFVII as "Final Oxymoron VII" -- how awesome is that?
Power Quest (1999, GBC)
-- It's easy to see why critics thought it was middling -- it's frequently unclear how to advance in the game, and all of the action in it is confined to one miniaturesquwe town. Still, taken for what it is, PQ redeems itself by being an RPG/fighter that's combat is endlessly enjoyable (and takes a cue from titles like the GB port of Street Fighter II) to the point of being a compulsion. Why hasn't there been more games in this genre?
Wario Land 3 (2000, GBC)
-- While largely untalked about now, this is without a doubt Nintendo's finest unsung foray into 2D platforming; highly inventive (getting hit by enemies is requisite for the purposes of transformation and puzzle-solving -- how's that for the anti-Mario?) and no lesser a title than totems such as Super Metroid
Conker's Bad Fur Day (2001, N64)
-- It's well-regarded, sure, but you rarely see credit being given where credit is due -- CBFD is as good as any game on the N64 (including, yes, Zelda 64), featuring arguably the N64's best graphics, a deeply hilarious single-player, and a multi-player that -- for its faults -- matched any on the console
Red Faction (PS2/PC, 2001)
-- Not highly underrated, and nor in the same league as GoldenEye/Half-Life/Jedi Knight, RF still is arguably the best FPS to follow Half-Life 1 and precede Half-Life 2 (assuming you consider Deux Ex and SS2 RPGs), using geo-mod technology to achieve pleasurably anarchic results (bald key hunts are remedied by shooting through the door; how about that for questioning fundamental assumptions) and somehow making it all work at a decent FPS rate in multi-player on the PS2. A better pick-up: the PC version, which features an expanded multi-player accomodating many more than two players.
Shenmue II (2002, XB)
-- In spite of the swelling fanbase it seems to have accrued in recent years, Shenmue II is still underrated, as its meditative rather than hyperbolic narration, aesthetically excellent design, and relative focus on representing real (rather than reel) life seem to firmly entrench it as the greatest JRPG of the twenty-first century's inaugaral decade
Batman Begins (2005, XB/PS2/GC)
-- I'd hesitate to call it a masterpiece, but the gameplay here is rock-solid -- your ability to instill fear in your enemies by the manipulating of your environment is ingenious, giving Batman his Spider-Man-web-swinging equivalency, and the game expertly complements the plot of the eponymous film by weaving together all its loose ends. Had Eurocom released a revamped sequel that expanded it into a sandbox (TDK?), it would've sold like gangbusters.
