Quest for Glory II Remake is (as you might expect) a remake of Quest for Glory II: Trial by Fire, the second chapter of Sierra's adventure-RPG series started with Quest for Glory I: So You Want To Be A Hero.
Designed by Lori Ann and Corey Cole, Quest for Glory is a perfect hybrid between adventure and RPG. Exploration and puzzles are just like adventure games, while the combat system and the character's growth are the ones you typically find in role-playing games.
AGD Interactive started this excellent remake in 2003, and the final version (2.0) was released in 2011. It features hand-drawn backgrounds, digitized character portraits, improved animations, and a few enhancements to the original game. You can download it for free. I guess it's what Sierra would have done if they decided to redo the game with VGA graphics, probably even better. You can see from the screenshots that the game is stunning. You simply cannot miss it.
