I'd submit Arenthyor for consideration, as we've got pretty mild food/rest/death restrictions. As has been mentioned, they primarily serve as game balancing choices that PCs can make or not make as they see fit (the food and rest systems, at least).
Food: If you have it and a bedroll in your inventory, great, you get some HP regain bonus when you rest. If not, that's ok, you just don't earn as much HP. You don't ever suffer from hunger.
Resting: Rest allowed every 6 minutes. Can't rest with Medium/Heavy armor on, but that's more to introduce the idea of 'challenge' into the resting period and not about realism (taking a risk to rest in the wilderness? Hope you don't get surprised by a hungry ogre...). We also have potions of Rest that enable you to accrue the benefits of rest without the healing. Also, Inns offer rooms that don't have even that requirement and provide for full HP regain.
Death: Xp loss and drop a backpack item, but you'll never lose a level from lost xp. And, the backpack item is recoverable. As long as you're in good favor with your god, you're good to go.
All-in-all, the systems we have are user-friendly and easy to learn. Nor are there a ton of them. What we do have supports RP or runs in the background. We do use custom content (Uses CEP 2.4 and some tileset haks) and our in-game tailor can help you get just the right look.
We have a friendly, growing community and some of the best RP you'll find. Check us out at
