Nothing inspired me more as a child than sitting down and experiencing a great role-playing adventure, where I got to decide who the main character was and what important skills they possessed. I've recently become engrossed in titles such as Mass Effect, Knights of the Old Republic, and The Elder Scrolls: Oblivion.
The classic 2D RPGs of the 90s have always provided an interesting contrast to western developers; my favorites including Earthbound, Final Fantasy Adventure, Secret of Mana, and Chrono Trigger.
RPG games and music fit together like hand and glove. What great RPG game can you think of that does not have an amazing score?
