DTE - If you've seen any semi-futuristic space marine shooter, you've seen Halo. Alternately, Shadow the Hedgehog has about as much run-n-gun to it, but better gameplay, and no MP.

Ultima's version was annoying. You had to make sure each character had their own supply of food and drink, etc… I liked the old Might and Magics; you had to buy food, but it was dealt with otherwise automatically. It only really became a concern if you spent a long time running through dungeons.

As I said, it doesn't matter. If the system is mostly in place, just tweak it so that food is optional. Works for both types of players.
