"Crappy games" you always loved.

MDK doesn't really belong here since it was a fantastic and well built game, but it went almost unnoticed when it was released: http://en.wikipedia.org/wiki/MDK_(video_game)

Carmageddon and Carmageddon 2 were also god damn fantastic games but had plenty of bugs.

Mount & Blade Warband

Pikachu Volleyball

Leisure Suit Larry: Love for Sail! (Larry 7)

Skyrim.

What, wrong thread ?

Syphon Filter

Tactical Ops!

I dont know about the scores but i only heard bad stuff about gothic 1 and 2, great game for me.
Lets not forget alpha protocol.

Borderlands count?... the phisics are terrible, the AI sometimes is stupid, and the cars... OH MY GOD THE CARS...
but i FUCKING LOVE THIS GAME...

and Musou Warriors orochi, i love it

Pokemons on Gameboy ;3

yoda stories : P

Why're you defining "underdog" as "got bad reviews?" Skies of Arcadia and Aquaria are vasty underappreciated, and they're truly excellent.

When I saw the title of this topic, I immediately thought "Alpha Protocol", probably because I actually read a critic use the word "crappy" to describe the gameplay. "Love" is probably too strong a word but I did think it was under-appreciated.
Although it probably helps that I got it when it was on sale for $2.

E.T. for the Atari 2600. trollface

Actually, that game and joke should be put in seperate landfills, across continents preferably. :D

On serious terms, I really enjoyed Iron Grip: Warlord despite the low-average to terrible scores it received. The steampunk-ish setting is awesome and the online multiplayer was fantastic....for the 1 game I managed to find. Yeah, unfortunately IG: Warlord's multiplayer is dead, but hey, the game is great! I played it last night actually! ^_^

Another close second would be Hunted: The Demon's Forge. Sure, it may not be very long and from what I can tell the co-op is extremely bugged (haven't tried it myself yet), but the gameplay is fantastic. The game is a great light RPG/action adventure game in various locales. The graphics are insane (well, there's a lot of blacks and grays, but hey, Limbo has that too and look how it did :P) on just medium-high settings as well.

Metro 2033 and Mafia, anyone?

Serious Sam 2 :3 Finally it's in Steam. I've bought it.

Well, the closest to 'crappy' for a favorite of mine would have to be NGEN Racing. I don't think it scored too high or became well known, but it gave me many hours of enjoyment. :)

Sequence. Mixed review but I'm gonna give it 9/10 just because it's fun and unique lol.

Final Fight: Streetwise
50 Cent: Bulletproof
Maybe because I played both with my cousin in good, old "my turn is after you fail" style, commenting on the playthrough etc. ;-)

Also, not really bad, but MAG was underrated. MANY people were talking crap about it, while when I played its beta and Bad Company 2 beta, I thought they really were on par. Maybe because of the fact that thanks to the official PS forums, I was able to play with an actual team that knew what to do, instead of a bunch of random people...

Homefront and Duke Nukem Forever. Heard many players laughing about these games and calling them worst games ever, but i totally enjoyed both.

Enjoyed Alpha Protocol, though now think it's crappy. Enjoyed Splinter Cell: Conviction, though now think it have nothing to do with stealth-like-games. Enjoyed Gears of War 3 - only the third one, as it's the most bright, intense and touching shooter for xbox i've ever seen. oh, almost forgot - Kane & Lynch 2: The Dog Days. Loved the concept

Kane and Lynch 2: Dog Days

Detailed environment, unique graphic style and bloody brutal

(some people consider these crappy, but I don't)
The Puzzle Quest games. God, so addictive and awesome.

Lost planet: Extreme Condition

No lost planet 2 was terrible even in my eyes, but I loved the first one.
