Highly doubtful that another Beta would open up anything new. If you can't decide if you want to buy the game after this past weekend's Beta you won't. The Beta was just enough to give everyone a taste of the game. I fucking loved it so they have my pre-order.
Me, too. It's not perfect and I have some quibbles that I submitted in the beta feedback process for whatever good it may do... and I hope a lot of people did this... but 30 percent off from GMG turns this into a no brainer for me.
