Wondering how this would work. 1. What time period would it be set in? Before the Fall, during the books, or after the books? The first might be unpopular because of limited cameos (you'd be restricted to Brom, Morzan, Galbatorix, and Oromis, and their dragons... that's really about it). The second one might be difficult because of plotting (unless you would go through the main quest as Eragon, but that would deny the whole point of having an RPG as opposed to any other genre of game - Skyrim is great because you can do anything and no one is telling you what to do or who to be; you make up your own character). The third option might also be unpopular because of Inheritance spoilers, although by the time it comes out, I doubt that'll matter. 2. What would the main quest be? I'd presume you'd take up the role of a Dragon Rider and go from there, and choose races from the books. If you're not setting it in Eragon's time in the books, then you'd have to think up a completely different plot, with a new villain - possibly a shade Rider, or something completely original? You'd possibly have to make things up, since the IC's lore isn't as wide-reaching and as detailed as something like LotR or Star Wars. I think it'd be also good if you 3. What would the side quests be? I think a good idea would be following different canon characters and having several of those linked in. For example: 4. How on earth would combat work? You'd need to come up with dragon-back combat. Which'd be difficult to code, since you lack combat on horseback as it is. You'd need new weapons to do that effectively - swords are too short - you'd need something with reach like a halberd or a glaive or a lance (lances tend to be one-use only weapons though), as well as bows + magic. You could also translate some already existing Skyrim illusion/alteration spells and shouts which you only tend to use once into longer phrases. So like, Kyne's Peace could be turned into your typical 'I am a dragon rider and mean you no harm' that they tend to use to calm animals & mother nature down. You'd just change the magic-animation into a phrase said aloud. Aside from that, since you can use most magic and combat simultaneously, would choosing between being a mage and a warrior and a thief be somewhat arbitrary?
