Trace memory was good, but short. I think I spent about 5-6 hours on it total, and that was traveling, so I wasn't paying 100% attention to it. It had a few annoying puzzles (scratch off rust, blow off dust, etc.) but overall was pretty decent.

Hotel Dusk had a decent story and was quite a bit longer. The art direction was fantastic too. Again, some annoying puzzles, but not a bad game overall. If you enjoy character development and character based story telling, I'd pick this up.

Personally, I'd get the Phoenix Wright games over both of these. Are there any other suggestions for good adventure games on the DS? I'm always looking for new ones!

Of the two Dusk wins.......but they are both good interactive novels.

Hotel Dusk is one of my favorite games, ever. It has a really cool noire atmosphere that no game has ever successfully emulated.

There is a great part where the main character is talking about drinking scotch, and how much the glass weighs, and "a good pour."

Just a classy game from a great developer. It's a must play, imo. Hotel Dusk, the most adult game on a console, lol.

...well, not "adult" more like "mature."
