Buy iTunes Gift Cards from any dealer on the Garage section.
Sim City & Monopoly were on sale $.99 for several time. You can wait for sale, don't know when or just buy with the current price. I only got monopoly, buy it if you love board game, love Monopoly and better if you have friends to play along. I bought Monopoly only mainly because of the local multiplayer mode.
CGS, although I got this game for free like tzxsean, I can assure you it's one of the best RPG available on the app store w/ great price, $4.99 (sale price 50% off, normally $9.99). Square Enix FF games cost = $8.99 each, very rare to have sale. Auto-save function is coming soon, the dev said so. You can save anywhere at anytime in game w/ 3 save slots right now, so just save frequently. Control - just learn how to use it, no complain from me for the control, easy to use once you learned the curve.
I don't see what is the point closing down the FaaDViP open registration - maybe they're doing some test. Public site is better, here is my invite code if anyone need it, if you missed the open registration last time:
