I've never played it but keep bumping into a few posts about this game from time to time. Looks like it be quite an uphill battle in time and investment to get somewhere on that.
Still is quite an interesting topic. I've played some real cash economy games in the past. Always found them more fun just trying to pull a slight profit then anything else. Looks like its a tad to late for anyone looking to get into this on the cheap and get anywhere.
