I played game of war for a few months... but "playing" isn't the right word. It became more like a responsibility and I found myself waking up and logging in before i got out of bed to keep my kingdom growing properly. I invested $24.99 total.
I got invited into a fast growing and surprisingly serious alliance and benefited from all of their activity. The more money they spent, the more gifts our alliance got. While I continued growing at a snails pace personally, I witnessed absolute INSANITY among other players. These schmucks are dropping $100 several times a week... sometimes several times a NIGHT to buy "gift packs". The gift packs start out $4.99 then disappear, then $19.99 (disappear), then $49.99 (disappear), and finally $99.99 - which is the ONLY pack these guys can buy now.
The company, machine zone is advertising everywhere and they can afford it. How? Do a little research and you will see that GOW is attracting 15k new users DAILY from all over the globe. Daily revenue is estimated at 500k. This is DAILY !!!!
In any case - I just stopped "playing" cold turkey. I left my kingdom (boo fcking hoo) and I have no interest in logging in to read any dramatic emails from other players. The game is a collossal waste of time and is't even fun. The attraction is for addictive personalities. The game becomes part of your everyday life if you want to maximize growth. I am so glad I am done with that garbage.
