Ive only been playing for a couple of days and the game seems great ... when i saw the top 2 players power they were the same.
I assumed they had rounded off their power points togeather to be balanced so they couldnt destroy each other but i then learnt that its maxed out.
I think it should be harder to get a squizzillon power points or i suggest that the top 5 players regardless of their difference in power should be entered into some sort of reduction scheme! ... ie like a sort of Gods Court where the judge can be like a Q Being (the site Administrators)  ... and their role would be to select some one out of the top 5 to be reduced in power to 6th place or something(why did you pick me type of thing)...

That way bieng in the top five would be very dangerous and maybe players would try and balance more with others instead of getting a gizzillion points and being able to destroy every one .

I dont know how much control you have over players accounts but if you could stop players in some way of wanting to max out then the game wont have to end in a dooms day scenario .... and the balance of power struggles would improve the game .

The gods court scenario is open to administrators creativity .. but again i dont know how much control you have over the game....

Just an Idea ...cheers
