Hmm, DSI has been involved in all of the following games:
SimCity 2000 - One of the worst GBA ports I've ever seen, with poor framerate, missing features, and sloppy controls
ATV: Thunder Ridge Riders - A mediocre GBA racing game, not worth the time.
A bunch of board game collections - They usually get the rules right, but make it un-fun with poor interfaces and bad controls.
A bunch of ports of Atari/Arcade games - Each time, they get it accurate, but manage to screw it up in some way or another, usually by not saving high scores.
Baldur's Gate: Dark Alliance - Surprisingly fun. Pretty much the only good DSI game.
Big Mutha Truckers - Features what appears to be the lowest framerate of any racing game ever made. The DS version is slightly less bad than the GBA version.
Deal or No Deal - How did they manage to ruin this? Because of its inherently empty concept, the game should have been all presentation. The only problem is, the presentation was annoying and ugly.
Medal of Honor Underground - It's like the original Doom, except blander.
Need for Speed: Porsche Unleashed - Another mediocre racing game. Not like they had a whole lot to work with, considering the console version was mediocre also.
R-Type III: The Third Lightning - It only looks looks like the SNES classic; the original didn't have poor collision detection, and the original was much faster, and the original didn't suck.
Rock 'em Sock 'em Robots - The worst excuse for a fighting game I've ever seen. Also, the biggest waste of a license I've ever seen. Imagine a simple button masher, but easier.
Harlem Globetrotters World Tour - The second biggest waste of a license I've ever seen. Its hideous graphics aren't recognizable as actual Globetrotters, even.
Snood - Stick with the classic Mac/PC shareware game, or just get Bust-A-Move/Puzzle Bobble. This piece of crap has vomit-inducing new sprites, annoying animations that waste your time, and broken aiming.
Snood 2: On Vacation - More of the same, but in addition to the GBA crap, now there's a DS version with a big pause button on the touch screen. This game could've made really good use of the touch screen, and that may have been enough to redeem it. What a pity.
Dr Seuss: How the Grinch Stole Christmas - It's not even out yet, but there's not really any way that this story could make a good game, whether they use the original book, the classic cartoon based on the original book, or the Jim Carrey movie barely inspired by the original book.
I haven't played B-17 Fortress in the Sky, but I'm assuming that it's just as bad.
