I would counsel against making RPs too 'gamey'.

I say there needs to be a level of gamey-ness to it to help keep the RP afloat. 
Otherwise you get a freeform NRP which don't tend to last long and people will also argue on their progress and such.
Personally I see no reason why you shouldn't use game-like concepts if they can work; there's a reason why strategy games exist and how some have become so famous, widespread and popular, no shaming in using some game concepts to improve and RP.
Its also not like we're asking people to play spread sheet simulator a la Aurora 4X style with heavy number crunching (and yes, I've been in those NRPs too)
