I'm a resource hoarder in almost any sort of game - couldn't play casters in 3.5, for instance. Use stealth and melee weapons in games like Deus Ex, not for the challenge, but because I don't want to waste bullets from something as basic as a pistol. I've gotten *better*, but...
I like 4E's Action Points, both from a resource management perspective and for what they do. I think, in a fairly long-term Eberron game I DMed, the party might have used... maybe half a dozen action points. Total. The entire group likes to hoard resources - they also resisted using potions and scrolls. In an Eberron game I played, I actually used a few, but often in exchange for being able to do something extraordinary, rather than as a bonus to a roll - worked well for my swashbuckler. So I think 4E Action Points will be a much better fit for my group.
