PASH is a game I have a lot of fondness for. It's a Flash adventure in which you must scour a dilapidated city to collect your scattered belongings and fight off the grrroms, wicked bug-monsters that terrorize everyone. You choose your own avatar, a combination of hip, photorealistic clothing and a cartoon body. This visual mix lends PASH its unusual flavor -- all the backgrounds are photos of abandoned, run-down urban locations, while all the characters and many of the objects are Flash cartoons. Add to that the funky electronic beats of the soundtrack and the odd, lilting quality of the characters' voices, and you get that unique PASH atmosphere that I can't quite define. Browsing the site's links, it seems that PASH is actually a Munich clothing manufacturer, which would explain the avatars' trendy threads -- though not much else about the game. Anyway, it's a quite fun, and nice to look at.
A couple of hints and help at the Nordinho forums, but it shouldn't really be necessary, as the game is pretty linear.
Peasant's Quest is a Homestar Runner parody of classic Sierra adventure game King's Quest. The graphics and game mechanics are just like the first several KQ games -- arrow keys to move, and type all commands, like "TALK KNIGHT." Features Homestar Runner's usual brand of humor -- a great take-off on the adventure games of old.

Inspektor Wombat is a very nice adventure game. You play a charming old German detective who collects numerous unusual objects, talks to people, and solves mysteries. The cartoonish animation is very cute and well-done. The game is German, but there is an English version. The commands, objects, descriptive text, and dialog are translated, but unfortunately, in-game texts -- such as the "blackmail letter" you begin the game with -- are left in German. I haven't played the whole game yet, so I don't know how much of an obstacle this is.
Help and a walkthrough are provided in the English forum, however.
As you may have noticed, these are all third-person adventure games. Up next: first-person (or "Myst-style") adventures, of which I have very many.
