I changed from 5 stars to 2 stars. For two reasons actually. I couldn't help but notice the constant adsence (forced) breakaways interrupting my play and thought process every 60 seconds massively taking away from the enjoyment. Lets face it, enjoyment is the reason we play these. When you take that away theres no reason to play. Barring the heavy ads I did enjoy it. So i thought I'd pay the 99 cents to stop the ads. I clicked stop ads and was hit with sticker shock...they want $6!! Uninstalled.
