I have an answer for peterwp42 which does not need to be sent via personal PM. Forge of Empire certainly can count as an economy empire building game. Myself and many others play this game without spending any money (sorry developers) and have a fine playing experience and are competitive in the game. I've personally been playing for 11 months, and made great progress. I typically am first, second or third in PvP play and have moved from being the 9,000th position from my first week of play to being one of the top 700 players in F world. If you have patience, get involved with a supportive guild. and learn the ins and outs, Forge of Empire can be fun for both premium paying players as well as those who like the challenge of advancing without spending money. P.S. Thanks to those of you who spend money on this game. I know you have a good time as well, and you help keep this game available for those of us who can't spend the money.
