DX:IW for fans of the first game, yes, it's horrid utter crap. The community has made better mods for DX1 (Zodiac shows off what Paul Denton would have done either just before or at the same time JC starts looking for the terrorist leader on Liberty Island) As a game by itself, it has standing power alone. I couldnt help notice though such high ratings most game sites gave this game, and looking in utter amazement. At first, I liked it first playthrough. Then after I figured out how to widen out the HUD and stuff, and apply the higher-quality graphics, I liked it a lot more, but comparing it to the first, it's a complete dissapointment. Apparently they tweaked the engine so much that it couldnt render water or something, due to limitations of the xbox I think, and that's why you'll get to a certain part that's all frozen over instead of having water all around like in the first game. There was a lot MORE they could have done with the game, and when the news broke that they axed the PC Code tree, a lot of hearts were broken over on the PC side, cause some of the early screenshots were very impressive. (Anyone remember at least the ATM shot, and the honeycomb HUD?) But HEY! for 10 bucks, it's worth a good playthrough. I'm bitter cause I spent 50 on it plus 12 for overnight shipping. Yes, I played the demo before I bought it, and I was hyped up like hell cause of it. After working through the whole thing it was another story though..
Oh yeah, if you play without JohnP's texture packs, look for ovbious blatant misspellings on very prominent places throughout the game. WTF were they thinking...
An underplayed and underappreciated game I liked a couple years back was Chaser. For a dumb, mindless FPS, it was fairly entertaining, but what was interesting about it, the engine was made by someone OTHER Than the big three (id, Epic, and Crytek) It was made by Cauldron, little known here back in the states. Another game I actually liked was one called Bandits, from the same developers that brought us the highly addictive Ballistics. Third-person vehicular Mad-Max style game. I got a kick outta that one. But as for newer games, I really thoroughly enjoy SWAT4, made by good ol' Irrational, using the Vengeance Engine, but I guess that's a pretty popular game. I cant think of any underappreciated games that are this new at the moment..
