U as in Anachronox, duh.
'Tis one of the finest role-playing games I've ever had pleasure to encounter. It doesn't require utterly-silly long period of time for upgrades, and you can follow the story without having to do some extra tasks if you will. The setting of this game is quite imaginative and gives you fine character backgrounds to explore and their stories to unfold. The entire Anachronox place is very likable and gives a constant thought "How cool would be to be there with Sly as he solves the cases, side by side." and all the levels are incredibly interesting and intriguing to explore. Dialogues are smartly written and overly humorous on occasion which boost up your spirit and don't let you get bored even for a second. Game runs very fast and has one of the finest mouse+keyboard combination for gameplay. The background music is relaxing and could loop infinitely without bothering you, yet creating a unique experience and compensates for all those vast dialogues you may take on for whatever side-quests you may be interested in.
Nothing much unless you go to extreme technicalities and start comparing its graphic to nowadays levels. You may have a slight loss on graphic quality, but rest assured speed is heavily gained.
The Bottom Line
A detective game with sci-fi and mystery elements made into helluva combination of light adventure and role-playing without troubling the player with some complicated learning curve.
The game features:
the ultra-cool main protagonist that always pulls the shortest straw in the fight... or love, being extremely funny especially when he's not aware of it
very unique and cool set of party members, each having interesting background story, and very easy to grow on you
lightning-fast controls (no, I didn't have my current configuration back then) and very easy navigable gameplay
intriguing storyline that will keep some turnover in the least expecting moment
very rich and detailed places to explore, people to talk to, and troubles to get into
one of the coolest striptease dance you'll ever see (though it doesn't beat how Sly wins the audience with his secret moves)
relaxing soundtrack working marvelously as a BGM
jokes and humorous hexes you'll remember for a lifetime
very interesting, yet not impossible SquareSoft-alike, final boss battle
