Anyone willing to make a list if non-traditional adventure games? By this I mean games whose style varied from say the classic Sierra style to feel very different. Different style of puzzles, strange hybrid moments, etc.
Inca & Inca II
Strange adventure that combined space simulator, rail shooters, maze shooter moments with classic adventure game inventory puzzles.
Another Zork adventure but incorporated an RPG element to the game. At the start you could even choose your own stats.
Quest for Glory 1-4
Another set of adventure games that incorporated RPG elements into adventure games. The fifth game switched genres into Action/RPG genre. It only maintained a few adventure elements.

An early true-3D adventure game. It incorporated some RPG and combat sequences. The player plays as an explorer in a rad suit, exploring an underground city filled with dinosaurs and templar knights. While solving Myst-style puzzles. There may have been inventory puzzles as well but it's been so long since I played it.
