I think maybe just some flowers here and there, not a long corridoor have it as a square big room with stalls in the middle and around so you run different directions. Break the mold. And have the NPC's do different things, could be just filing a sword if they have one for sale, or talking with other npcs (with no dialogue just the illusion), sitting down, resting on crates etc. Anything that gives it life would do me =)

I dont mind the system i just hate how dull it is, so thats my only issue!
