I've been tinkering with the rules for a fantasy thing my group is playing, and realized that, waitaminute, the skill list I'm developing towards is almost the same as the skill list used in Oblivion, and breaks down into "Apprentice, Journeyman, Expert", and such, though not actual percentiles. Swapping the stats for Oblivion stats (including fatigue, health, and magic pools) would likewise be dirt-easy.
I'm now tempted to just go with it, and hammer down a few extra pages to match things up more tightly.
So, let's say you got an Elder Scrolls fan-game dropped in front of you. Bare bones, just "how to do things", "how to make characters", and "combat and adventuring"
What would you think was an absolute must-have in such a game? What would make you cringe if you saw it ported over?
